耐盐雾等级英语Corrosion Resistance: The Importance of Salt Spray TestingCorrosion is a significant concern for a wide range of industries, from automotive and aerospace to marine and construction. The ability of materials to withstand the effects of environmental exposure, particularly to salt and moisture, is a critical factor in ensuring the longevity and reliability of products and structures. One of the key tools used to assess a material's corrosion resistance is the salt spray test, also known as the salt fog test or the salt mist test.The salt spray test is a standardized laboratory procedure that simulates the exposure of materials to a corrosive environment, typically one containing a salt solution. The test involves subjecting the material samples to a fine mist or fog of a saline solution, usually a 5% sodium chloride (NaCl) solution, for a specified duration. The samples are then inspected for signs of corrosion, such as pitting, rusting, or other forms of degradation.The salt spray test is a valuable tool for several reasons. First and foremost, it provides a controlled and repeatable way to evaluate the corrosion resistance of materials. By exposing samples to aconsistent, accelerated corrosive environment, the test can help predict how the material will perform in real-world conditions. This information is crucial for product development, quality control, and failure analysis.Moreover, the salt spray test is widely recognized and accepted as a standard method for assessing corrosion resistance. Many industries and regulatory bodies have established specific requirements or guidelines for salt spray testing, ensuring that products meet certain performance thresholds. This standardization allows for effective comparison of materials and ensures that products meet the necessary safety and reliability standards.The salt spray test is not limited to a single application or industry. It is used extensively in the automotive industry to evaluate the corrosion resistance of paints, coatings, and metal components. In the aerospace industry, the test is used to assess the performance of aircraft materials, such as the skin, fasteners, and electronic components, which are exposed to harsh environmental conditions during flight.In the marine industry, the salt spray test is crucial for evaluating the corrosion resistance of materials used in boats, ships, and offshore structures. These environments are particularly challenging, as they are constantly exposed to saltwater, humidity, and other corrosiveelements.The construction industry also relies on the salt spray test to ensure the durability of building materials, such as steel, concrete, and coatings, in environments prone to salt exposure, such as coastal regions or areas with high levels of road salt usage.Beyond these industries, the salt spray test is also used in the development of consumer electronics, household appliances, and various other products that may be exposed to corrosive environments during their lifetime.The salt spray test is not a one-size-fits-all solution, however. The specific test parameters, such as the duration, salt concentration, and temperature, can be tailored to simulate different real-world conditions. This flexibility allows researchers and engineers to design tests that accurately reflect the environments their products will encounter.Moreover, the salt spray test is just one of many tools used to assess corrosion resistance. Other methods, such as electrochemical testing, exposure to natural environments, and accelerated weathering, can provide complementary information and help paint a more comprehensive picture of a material's performance.In conclusion, the salt spray test is a critical tool for evaluating the corrosion resistance of materials and ensuring the long-term reliability and safety of products across a wide range of industries. By providing a standardized, controlled, and repeatable way to assess corrosion, the salt spray test has become an essential part of the product development and quality assurance process. As environmental conditions continue to pose challenges to materials, the importance of the salt spray test will only continue to grow, ensuring that the products we rely on remain durable, safe, and fit for purpose.。

Designation:B 117–07Standard Practice forOperating Salt Spray (Fog)Apparatus 1This standard is issued under the fixed designation B 117;the number immediately following the designation indicates the year of original adoption or,in the case of revision,the year of last revision.A number in parentheses indicates the year of last reapproval.A superscript epsilon (e )indicates an editorial change since the last revision or reapproval.This standard has been approved for use by agencies of the Department of Defense.1.Scope1.1This practice covers the apparatus,procedure,and conditions required to create and maintain the salt spray (fog)test environment.Suitable apparatus which may be used is described in Appendix X1.1.2This practice does not prescribe the type of test speci-men or exposure periods to be used for a specific product,nor the interpretation to be given to the results.1.3The values stated in SI units are to be regarded as the standard.The values given in parentheses are for information only.1.4This standard does not purport to address all of the safety concerns,if any,associated with its use.It is the responsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.2.Referenced Documents 2.1ASTM Standards:2B 368Test Method for Copper-Accelerated Acetic Acid-Salt

Interlaboratory Study to Determine the Precision of a Test MethodG 85Practice for Modified Salt Spray (Fog)Testing3.Significance and Use3.1This practice provides a controlled corrosive environ-ment which has been utilized to produce relative corrosion resistance information for specimens of metals and coated metals exposed in a given test chamber.3.2Prediction of performance in natural environments has seldom been correlated with salt spray results when used as stand alone data.3.2.1Correlation and extrapolation of corrosion perfor-mance based on exposure to the test environment provided by this practice are not always predictable.3.2.2Correlation and extrapolation should be considered only in cases where appropriate corroborating long-term atmo-spheric exposures have been conducted.3.3The reproducibility of results in the salt spray exposure is highly dependent on the type of specimens tested and the evaluation criteria selected,as well as the control of the operating variables.In any testing program,sufficient repli-cates should be included to establish the variability of the results.Variability has been observed when similar specimens are tested in different fog chambers even though the testing conditions are nominally similar and within the ranges speci-fied in this practice.4.Apparatus4.1The apparatus required for salt spray (fog)exposure consists of a fog chamber,a salt solution reservoir,a supply of suitably conditioned compressed air,one or more atomizing nozzles,specimen supports,provision for heating the chamber,and necessary means of control.The size and detailed con-struction of the apparatus are optional,provided the conditions obtained meet the requirements of this practice.4.2Drops of solution which accumulate on the ceiling or cover of the chamber shall not be permitted to fall on the specimens being exposed.1This practice is under the jurisdiction of ASTM Committee G01on Corrosion of Metals and is the direct responsibility of Subcommittee G01.05on Laboratory Corrosion Tests.Current edition approved March 1,2007.Published March 2007.Originally approved in st previous edition approved in 2003as B 117–03.2For referenced ASTM standards,visit the ASTM website,,or contact ASTM Customer Service at service@.For Annual Book of ASTM Standards volume information,refer to the standard’s Document Summary page on the ASTM website.Copyright ©ASTM International,100Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959,United States.w ww .b zf xw .c o4.3Drops of solution which fall from the specimens shall not be returned to the solution reservoir for respraying.4.4Material of construction shall be such that it will not affect the corrosiveness of the fog.4.5All water used for this practice shall conform to Type IV water in Specification D 1193(except that for this practice limits for chlorides and sodium may be ignored).This does not apply to running tap water.All other water will be referred to as reagent grade.5.Test Specimens5.1The type and number of test specimens to be used,as well as the criteria for the evaluation of the test results,shall be defined in the specifications covering the material or product being exposed or shall be mutually agreed upon between the purchaser and the seller.6.Preparation of Test Specimens6.1Specimens shall be suitably cleaned.The cleaning method shall be optional depending on the nature of the surface and the contaminants.Care shall be taken that specimens are not recontaminated after cleaning by excessive or careless handling.6.2Specimens for the evaluation of paints and other organic coatings shall be prepared in accordance with applicable specification(s)for the material(s)being exposed,or as agreed upon between the purchaser and the supplier.Otherwise,the test specimens shall consist of steel meeting the requirements of Practice D 609and shall be cleaned and prepared for coating in accordance with the applicable procedure of Practice D 609.6.3Specimens coated with paints or nonmetallic coatings shall not be cleaned or handled excessively prior to test.6.4Whenever it is desired to determine the development of corrosion from an abraded area in the paint or organic coating,a scratch or scribed line shall be made through the coating with a sharp instrument so as to expose the underlying metal before testing.The conditions of making the scratch shall be as defined in Test Method D 1654,unless otherwise agreed upon between the purchaser and the seller.6.5Unless otherwise specified,the cut edges of plated,coated,or duplex materials and areas containing identification marks or in contact with the racks or supports shall be protected with a suitable coating stable under the conditions of the practice.N OTE 1—Should it be desirable to cut test specimens from parts or from preplated,painted,or otherwise coated steel sheet,the cut edges shall be protected by coating them with paint,wax,tape,or other effective media so that the development of a galvanic effect between such edges and the adjacent plated or otherwise coated metal surfaces,is prevented.7.Position of Specimens During Exposure7.1The position of the specimens in the salt spray chamber during the test shall be such that the following conditions are met:7.1.1Unless otherwise specified,the specimens shall be supported or suspended between 15and 30°from the vertical and preferably parallel to the principal direction of flow of fog through the chamber,based upon the dominant surface being tested.7.1.2The specimens shall not contact each other or any metallic material or any material capable of acting as a wick.7.1.3Each specimen shall be placed to permit unencum-bered exposure to the fog.7.1.4Salt solution from one specimen shall not drip on any other specimen.N OTE 2—Suitable materials for the construction or coating of racks and supports are glass,rubber,plastic,or suitably coated wood.Bare metal shall not be used.Specimens shall preferably be supported from the bottom or the side.Slotted wooden strips are suitable for the support of flat panels.Suspension from glass hooks or waxed string may be used as long as the specified position of the specimens is obtained,if necessary by means of secondary support at the bottom of the specimens.8.Salt Solution8.1The salt solution shall be prepared by dissolving 561parts by mass of sodium chloride in 95parts of water conforming to Type IV water in Specification D 1193(except that for this practice limits for chlorides and sodium may be ignored).Careful attention should be given to the chemical content of the salt.The salt used shall be sodium chloride with not more than 0.3%by mass of total impurities.Halides (Bromide,Fluoride,and Iodide)other than Chloride shall constitute less than 0.1%by mass of the salt content.Copper content shall be less than 0.3ppm by mass.Sodium chloride containing anti-caking agents shall not be used because such agents may act as corrosion inhibitors.See Table 1for a listing of these impurity restrictions.Upon agreement between the purchaser and the seller,analysis may be required and limitsTABLE 1Maximum Allowable Limits for Impurity Levels inSodium Chloride A ,B ,CImpurity DescriptionAllowable AmountTotal Impurities#0.3%Halides (Bromide,Fluoride and Iodide)excluding Chloride <0.1%Copper<0.3ppm Anti-caking AgentsnoneAA common formula used to calculate the amount of salt required by mass to achieve a 5%salt solution of a known mass of water is:0.0533Mass of Water 5Mass of NaCl requiredThe mass of water is 1g per 1mL.To calculate the mass of salt required in grams to mix 1L of a 5%salt solution,multiply 0.053by 1000g (35.27oz,the mass of 1L of water).This formula yields a result of 53g (1.87oz)of NaCl required for each liter of water to achieve a 5%salt solution by mass.The 0.053multiplier for the sodium chloride used above is derived by the following:1000g ~mass of a full L of water !divided by 0.95~water is only 95%of the total mixture by mass !yields 1053gThis 1053g is the total mass of the mixture of one L of water with a 5%sodium chloride concentration.1053g minus the original weight of the L of water,1000g,yields 53g for the weight of the sodium chloride.53g of total sodium chloride divided by the original 1000g of water yields a 0.053multiplier for the sodium chloride.As an example:to mix the equivalent of 200L (52.83gal)of 5%sodium chloride solution,mix 10.6kg (23.37lb)of sodium chloride into 200L (52.83gal)of water.200L of water weighs 200000g.200000g of water 30.053(sodium chloride multiplier)=10600g of sodium chloride,or 10.6kg.BIn order to ensure that the proper salt concentration was achieved when mixing the solution,it is recommended that the solution be checked with either a salimeter hydrometer or specific gravity hydrometer.When using a salimeter hydrometer,the measurement should be between 4and 6%at 25°C (77°F).When using a specific gravity hydrometer,the measurement should be between 1.0255and 1.0400at 25°C (77°F).CIf the purity of the salt used is >99.9%,then the limits for halides can be ignored.This is due to the fact that the halides cannot be $0.1%with a salt purity of >99.9%.If the salt used is of lower purity,then test forhalides.--````````,`,,,`,``,`,`,`````-`-`,,`,,`,`,,`---w ww .b zf xw .c oestablished for elements or compounds not specified in the chemical composition given above.8.2The pH of the salt solution shall be such that when atomized at 35°C (95°F)the collected solution will be in the pH range from 6.5to 7.2(Note 3).Before the solution is atomized it shall be free of suspended solids (Note 4).The pH measurement shall be made at 25°C (77°F)using a suitable glass pH-sensing electrode,reference electrode,and pH meter system in accordance with Test Method E 70.N OTE 3—Temperature affects the pH of a salt solution prepared from water saturated with carbon dioxide at room temperature and pH adjust-ment may be made by the following three methods:(1)When the pH of a salt solution is adjusted at room temperature,and atomized at 35°C (95°F),the pH of the collected solution will be higher than the original solution due to the loss of carbon dioxide at the higher temperature.When the pH of the salt solution is adjusted at room temperature,it is therefore necessary to adjust it below 6.5so the collected solution after atomizing at 35°C (95°F)will meet the pH limits of 6.5to 7.2.Take about a 50-mL sample of the salt solution as prepared at room temperature,boil gently for 30s,cool,and determine the pH.When the pH of the salt solution is adjusted to 6.5to 7.2by this procedure,the pH of the atomized and collected solution at 35°C (95°F)will come within this range.(2)Heating the salt solution to boiling and cooling to 35°C (95°F)and maintaining it at 35°C (95°F)for approximately 48h before adjusting the pH produces a solution the pH of which does not materially change when atomized at 35°C (95°F).(3)Heating the water from which the salt solution is prepared to 35°C (95°F)or above,to expel carbon dioxide,and adjusting the pH of the salt solution within the limits of 6.5to 7.2produces a solution the pH of which does not materially change when atomized at 35°C (95°F).N OTE 4—The freshly prepared salt solution may be filtered or decanted before it is placed in the reservoir,or the end of the tube leading from the solution to the atomizer may be covered with a double layer of cheesecloth to prevent plugging of the nozzle.N OTE 5—The pH can be adjusted by additions of dilute ACS reagent grade hydrochloric acid or sodium hydroxide solutions.9.Air Supply9.1The compressed air supply to the Air Saturator Tower shall be free of grease,oil,and dirt before use by passing through well-maintained filters.(Note 6)This air should be maintained at a sufficient pressure at the base of the Air Saturator Tower to meet the suggested pressures of Table 2at the top of the Air Saturator Tower.N OTE 6—The air supply may be freed from oil and dirt by passing it through a suitable oil/water extractor (that is commercially available)to stop any oil from reaching the Air Saturator Tower.Many oil/water extractors have an expiration indicator,proper preventive maintenance intervals should take these into account.9.2The compressed air supply to the atomizer nozzle or nozzles shall be conditioned by introducing it into the bottomof a tower fillwed with water.A common method of introduc-ing the air is through an air dispersion device (X1.4.1).The level of the water must be maintained automatically to ensure adequate humidification.It is common practice to maintain the temperature in this tower between 46and 49°C (114–121°F)to offset the cooling effect of expansion to atmospheric pressure during the atomization process.Table 2shows the temperature,at different pressures,that are commonly used to offset the cooling effect of expansion to atmospheric pressure.9.3Careful attention should be given to the relationship of tower temperature to pressure since this relationship can have a direct impact to maintaining proper collection rates (Note 7).It is preferable to saturate the air at temperatures well above the chamber temperature as insurance of a wet fog as listed in Table 2.N OTE 7—If the tower is run outside of these suggested temperature and pressure ranges to acheive proper collection rates as described in 10.2of this practice,other means of verifying the proper corrosion rate in the chamber should be investigated,such as the use of control specimens (panels of known performance in the test conducted).It is preferred that control panels be provided that bracket the expected test specimen performance.The controls allow for the normalization of test conditions during repeated running of the test and will also allow comparisons of test results from different repeats of the same test.(Refer to Appendix X3,Evaluation of Corrosive Conditions,for mass loss procedures).10.Conditions in the Salt Spray Chamber10.1Temperature —The exposure zone of the salt spray chamber shall be maintained at 3562°C (9563°F).Each set point and its tolerance represents an operational control point for equilibrium conditions at a single location in the cabinet which may not necessarily represent the uniformity of condi-tions throughout the cabinet.The temperature within the exposure zone of the closed cabinet shall be recorded (Note 8)at least once daily (except on Saturdays,Sundays,and holidays when the salt spray test is not interrupted for exposing,rearranging,or removing test specimens or to check and replenish the solution in the reservoir)N OTE 8—A suitable method to record the temperature is by a continu-ous recording device or by a thermometer which can be read from outside the closed cabinet.The recorded temperature must be obtained with the salt spray chamber closed to avoid a false low reading because of wet-bulb effect when the chamber is open.10.2Atomization and Quantity of Fog —Place at least two clean fog collectors per atomizer tower within the exposure zone so that no drops of solution will be collected from the test specimens or any other source.Position the collectors in the proximity of the test specimens,one nearest to any nozzle and the other farthest from all nozzles.A typical arrangement is shown in Fig.1.The fog shall be such that for each 80cm 2(12.4in.2)of horizontal collecting area,there will be collected from 1.0to 2.0mL of solution per hour based on an average run of at least 16h (Note 9).The sodium chloride concentration of the collected solution shall be 561mass %(Notes 9-11).The pH of the collected solution shall be 6.5to 7.2.The pH measurement shall be made as described in 8.2(Note 3).N OTE 9—Suitable collecting devices are glass or plastic funnels withTABLE 2Suggested Temperature and

crystal-lizing dishes.Funnels and dishes with a diameter of 10cm (3.94in.)have an area of about 80cm 2(12.4in.2).N OTE 10—A solution having a specific gravity of 1.0255to 1.0400at 25°C (77°F)will meet the concentration requirement.The sodium chloride concentration may also be determined using a suitable salinity meter (for example,utilizing a sodium ion-selective glass electrode)or colorimetrically as follows.Dilute 5mL of the collected solution to 100mL with distilled water and mix thoroughly;pipet a 10-mL aliquot into an evaporating dish or casserole;add 40mL of distilled water and 1mL of 1%potassium chromate solution (chloride-free)and titrate with 0.1N silver nitrate solution to the first appearance of a permanent red coloration.A solution that requires between 3.4and 5.1mL of 0.1N silver nitrate solution will meet the concentration requirements.N OTE 11—Salt solutions from 2to 6%will give the same results,though for uniformity the limits are set at 4to 6%.10.3The nozzle or nozzles shall be so directed or baffled that none of the spray can impinge directly on the test specimens.11.Continuity of Exposure11.1Unless otherwise specified in the specifications cover-ing the material or product being tested,the test shall be continuous for the duration of the entire test period.Continu-ous operation implies that the chamber be closed and the spray operating continuously except for the short daily interruptions necessary to inspect,rearrange,or remove test specimens,to check and replenish the solution in the reservoir,and to make necessary recordings as described in Section 10.Operations shall be so scheduled that these interruptions are held to a minimum.12.Period of Exposure12.1The period of exposure shall be as designated by the specifications covering the material or product being tested or as mutually agreed upon between the purchaser and the seller.N OTE 12—Recommended exposure periods are to be as agreed upon between the purchaser and the seller,but exposure periods of multiples of 24h are suggested.13.Cleaning of Tested Specimens13.1Unless otherwise specified in the specifications cover-ing the material or product being tested,specimens shall be treated as follows at the end of the test:13.1.1The specimens shall be carefully removed.13.2Specimens may be gently washed or dipped in clean running water not warmer than 38°C (100°F)to remove salt deposits from their surface,and then immediately dried.14.Evaluation of Results14.1A careful and immediate examination shall be made as required by the specifications covering the material or product being tested or by agreement between the purchaser and the seller.15.Records and Reports15.1The following information shall be recorded,unless otherwise prescribed in the specifications covering the material or product being tested:15.1.1Type of salt and water used in preparing the salt solution,15.1.2All readings of temperature within the exposure zone of the chamber,15.1.3Daily records of data

APPARATUSX1.1CabinetsX1.1.1Standard salt spray cabinets are available from several suppliers,but certain pertinent accessories are required before they will function according to this practice and provide consistent control for duplication of results.X1.1.2The salt spray cabinet consists of the basic chamber,an air-saturator tower,a salt solution reservoir,atomizing nozzles,specimen supports,provisions for heating the cham-ber,and suitable controls for maintaining the desired tempera-ture.X1.1.3Accessories such as a suitable adjustable baffle or central fog tower,automatic level control for the salt reservoir,and automatic level control for the air-saturator tower are pertinent parts of the apparatus.X1.1.4The size and shape of the cabinet shall be such that the atomization and quantity of collected solution is within the limits of this practice.X1.1.5The chamber shall be made of suitably inert mate-rials such as plastic,glass,or stone,or constructed of metal and lined with impervious plastics,rubber,or epoxy-type materials or equivalent.X1.1.6All piping that contacts the salt solution or spray should be of inert materials such as plastic.Vent piping should be of sufficient size so that a minimum of back pressure exists and should be installed so that no solution is trapped.The exposed end of the vent pipe should be shielded from extreme air currents that may cause fluctuation of pressure or vacuum in the cabinet.X1.2Temperature ControlX1.2.1The maintenance of temperature within the salt chamber can be accomplished by several methods.It is generally desirable to control the temperature of the surround-ings of the salt spray chamber and to maintain it as stable as possible.This may be accomplished by placing the apparatus in a constant-temperature room,but may also be achieved by surrounding the basic chamber of a jacket containing water or air at a controlled temperature.X1.2.2The use of immersion heaters in an internal salt solution reservoir or within the chamber is detrimental whereheat losses are appreciable because of solution evaporation andradiant heat on the specimens.X1.3Spray NozzlesX1.3.1Satisfactory nozzles may be made of hard rubber,plastic,or other inert materials.The most commonly used type is made of plastic.Nozzles calibrated for air consumption and solution-atomized are available.The operating characteristics of a typical nozzle are given in Table X1.1.X1.3.2It can readily be seen that air consumption is relatively stable at the pressures normally used,but a marked reduction in solution sprayed occurs if the level of the solution is allowed to drop appreciably during the test.Thus,the level of the solution in the salt reservoir must be maintained automatically to ensure uniform fog delivery during the test.3X1.3.3If the nozzle selected does not atomize the salt solution into uniform droplets,it will be necessary to direct the spray at a baffle or wall to pick up the larger drops and prevent them from impinging on the test specimens.Pending a com-plete understanding of air-pressure effects,and so forth,it is important that the nozzle selected shall produce the desired3A suitable device for maintaining the level of liquid in either the saturator tower or reservoir of test solution may be designed by a local engineering group,or it may be purchased from manufacturers of test cabinets as an accessory.TABLE X1.1Operating Characteristics of Typical Spray NozzleSiphon Height ,cm Air Flow,dm 3/min Solution Consumption,cm 3/hAir Pressure,kPa Air

when operated at the air pressure selected.Nozzles are not necessarily located at one end,but may be placed in the center and can also be directed vertically up through a suitable tower.X1.4Air for AtomizationX1.4.1The air used for atomization must be free of grease,oil,and dirt before use by passing through well-maintained filters.Room air may be compressed,heated,humidified,and washed in a water-sealed rotary pump if the temperature of the water is suitably controlled.Otherwise cleaned air may be introduced into the bottom of a tower filled with water through a porous stone or multiple nozzles.The level of the water must be maintained automatically to ensure adequate humidification.A chamber operated in accordance with this method and Appendix X1will have a relative humidity between 95and 98%.Since salt solutions from 2to 6%will give the same results (though for uniformity the limits are set at 4to 6%),it is preferable to saturate the air at temperatures well above the chamber temperature as insurance of a wet fog.Table X1.2shows the temperatures,at different pressures,that are required to offset the cooling effect of expansion to atmospheric pressure.X1.4.2Experience has shown that most uniform spray chamber atmospheres are obtained by increasing the atomizing air temperature sufficiently to offset heat losses,except those that can be replaced otherwise at very low-temperature gradi-ents.X1.5Types of ConstructionX1.5.1A modern laboratory cabinet is shown in Fig.X1.1.Walk-in chambers are usually constructed with a sloping ceiling.Suitably located and directed spray nozzles avoid ceiling accumulation and drip.Nozzles may be located at the ceiling,or 0.91m (3ft)from the floor directed upward at 30to 60°over a passageway.The number of nozzles depends on type and capacity and is related to the area of the test space.An 11to 19L (3to 5-gal)reservoir is required within the chamber,with the level controlled.The major features of a walk-in type cabinet,which differs significantly from the laboratory type,are illustrated in Fig.X1.2.Construction of a plastic nozzle,such as is furnished by several suppliers,is shown in Fig.X1.3.TABLE X1.2Temperature and

EISThe water content in coating can also be determined by measuringmethod. The principle is water phaseThe dielectric constant (78.3 at 25) is higher than that of polymerThe constant (3-8) is much higher, so the water absorption can lead to the dielectric constant of the coating filmThe film capacitance increases if the number is increased (if the coating is regarded as flat)Andante capacitor, capacitance is C= E E oA/d, which offers for air.The dielectric constant, A is the coating area and D is the coating thicknessThe BK formula (Brasher-Kingsbury) shown in formula (3) is obtainedThe relationship between the volume fraction of water in coating and instantaneous capacitance Ct(D W=1g (Ct/Co) /1g ("W>" (formula 3)Co is a dry film capacitor, which is usually extrapolated to t=0 by curveThe capacitance of the film, F W as the dielectric constant of water.And one can get closer to the actual value than the BK formulaThe formula for the value obtained by the weighing method is:Wanfang DataAnalysis, testing, 2004(Dw two (C-C0) /Cw (formula 4)The solution capacitance is Cw= E W "oA/d o"It can be said that EIS technology provides an excellent test of film coatingDecay properties and other properties such as thermal properties, water solubility, and physical agingThe method of chemical process2.2 other commonly used modern coatings to evaluate the corrosion resistance of precoated coil coatingsAnalysis method2.2.1 fluorescent probe techniqueFluorescent probes can be used to study the properties of polymersEnergy, such as polymer compatibility, relaxation, absorptionof water in the coating andDistribution and reaction kinetics, the sensitivity of fluorescent probes to metal ionsProperties and selectivity can be used to detect the corrosion process of metalsThe advantage of the method is that the film can be destroyed without damaging the coating and can be used to characterize the protective propertiesThe coating can be quantitatively obtained by early degradation or corrosion damageThe corresponding fluorescence probes were used for different ionsFrom the fluorescence spectrum we can observe the protection of the metal under the coatingThe corrosion and corrosion processes can be observed from the fluorescence images on the interfaceThe corrosion area and corrosion degree appear2.2.2 open circuit voltage (OCP), scanning reference electrode technique (SRET)Electrochemical noise measurement (EN) techniqueChange of open circuit voltage (OCP) from coated metal substrateIt can be seen that the change of water content and ion penetration adsorption amount in coating filmOCP can be used to predict the sample size effectivelyTime to steady state, i.e. corrosion failure time.

Date: [Insert Date]Test Conducted By: [Insert Name]Department: [Insert Department]Introduction:The salt spray test, also known as the salt fog test, is a method used to determine the corrosion resistance of materials under the influence of a salt spray environment. This test is commonly employed in the automotive, aerospace, and other industries to assess the durability and reliability of materials under harsh conditions. The present report outlines the procedures, results, and conclusions of the salt spray test conducted on [Insert Material/Component Name].Materials and Equipment:- Test samples: [Insert Material/Component Name]- Salt spray test chamber- Distilled water- Sodium chloride (NaCl) pellets- pH test strips- Magnifying glass- Weighing scale- Data recording sheetTest Procedure:1. Preparation of the salt spray solution:- Dissolve 50g of sodium chloride in 1 liter of distilled water.- Adjust the pH of the solution to 6.5 ± 0.5 using 5M sodium hydroxide or hydrochloric acid.- Ensure that the solution is free from impurities and properly mixed.2. Sample preparation:- Clean the test samples thoroughly to remove any surface contaminants.- Dry the samples at room temperature for at least 24 hours.- Weigh the samples and record their initial weights.3. Salt spray test:- Place the samples in the salt spray test chamber, ensuring that they are evenly spaced.- Adjust the temperature of the test chamber to 35 ± 2°C.- Set the relative humidity to 95 ± 5%.- Maintain the salt spray condition for the required duration (e.g., 24, 48, or 96 hours).4. Post-test evaluation:- Remove the samples from the test chamber and rinse them with distilled water to remove any residual salt spray.- Dry the samples at room temperature for at least 24 hours.- Inspect the samples visually using a magnifying glass for any signs of corrosion.- Record the observations on the data recording sheet.Results:- The test samples were exposed to salt spray for [Insert Duration] hours.- During the test, the pH of the salt spray solution was maintained at 6.5 ± 0.5.- The temperature and relative humidity of the test chamber were within the specified limits.- Post-test evaluation revealed the following observations:Sample A:- Initial weight: [Insert Weight]- Final weight: [Insert Weight]- Corrosion rating: [Insert Rating (e.g., 1 = No corrosion, 5 = Severe corrosion)]Sample B:- Initial weight: [Insert Weight]- Final weight: [Insert Weight]- Corrosion rating: [Insert Rating]Sample C:- Initial weight: [Insert Weight]- Final weight: [Insert Weight]- Corrosion rating: [Insert Rating]Conclusions:Based on the results of the salt spray test, the following conclusions can be drawn:1. The [Insert Material/Component Name] exhibited good corrosion resistance under the test conditions.2. The test duration of [Insert Duration] hours was sufficient to evaluate the corrosion resistance of the material.3. The pH of the salt spray solution was within the specified range, ensuring accurate test results.4. The temperature and relative humidity of the test chamber were maintained within the required limits, ensuring reliable results.Recommendations:- Further research is recommended to investigate the effects of different salt spray durations and intensities on the corrosion resistance of the material.- The test procedure can be modified to include other environmental factors, such as temperature and humidity, to simulate real-world conditions more accurately.- Additional tests, such as accelerated corrosion tests, can be conducted to validate the findings of the salt spray test.[End of Report]。
