永磁材料发展史
第一章．文献综述1.1前言21世纪是电子化的时代。
永磁材料作为电子工业的一种基础功能材料，已经渗透到人类生产、生活的各个领域, 在汽车、摩托车、电视机、音响、计算机、通信终端机、医疗仪器等方面获得了广泛的应用。
永磁材料可以实现能量的转换、传输以及信息传输、存储等功能，已成为现代科学技术，如计算机技术、信息技术、航空航天技术、通讯技术、交通运输(汽车)技术、办公自动化技术、家电技术与人体健康和保健技术等的重要物质基础[1]。
永磁材料以其典型的节能、节材及出口创汇产品和在现代高新技术产业中不可低估的作用，而被专家人士认为是衡量一个国家经济发展程度的指标，粗略体现一个国家的国民生活水平。
1.2 永磁材料特性及发展概况1.2.1 永磁材料特性永磁材料和软磁材料的主要区别是永磁材料的各向异性场(H A)高，矫顽力(H C)高，磁滞回线面积大，磁化到技术饱和需要的磁化场大。
现代永磁材料的矫顽力一般均大于4000kA/m，而软磁材料的矫顽力一般小于80A/m，最低仅0.08A/m 左右。
永磁材料的主要技术性能指标是剩磁Br、矫顽力Hc(内禀矫顽力Hcj和磁感矫顽力Hcb )、磁能积(BH)max及温度系数等参量。
图1-1为典型的永磁材料磁滞回线[1]1、矫顽力分为磁感矫顽力(Hcb或bHc)和内桌矫顽力，磁感矫顽力是退磁曲线上B=0对应的磁场，相应于磁滞回线与横坐标的交点(见图1一1)。
Hcb是表征永磁材料对外界磁场的抗干扰能力。
内禀矫顽力(Hcj、jHc或mHc)是使内禀磁感应强度 o M(或4πM)为零的反向磁场强度，Hc j≥Hcb。
Hcj的极限值是磁晶各向异性场H A，它取决于材料的磁晶各向异性常数。
2、剩磁感应强度Br，它是指磁化至技术饱和并去掉外场后所保留的剩余磁化强度Mr，相当于磁滞回线与纵坐标的交点(见图1一I)。
剩磁是表征永磁材料充磁后所提供的磁场大小的参量。
因此，Br越大越好。
Br的极限值是Js, Js取决于组成该材料的磁性原子数和原子磁矩的大小。

磷化工艺对铁基软磁复合材料电磁性能的影响
磷化工艺对铁基软磁复合材料电磁性能的影响李发长;李一;柳学全;贾成厂;李楠;李金普;霍静【摘要】The effect of phosphating process on the magnetic and electrical properties of Fe-based soft magnetic composites （SMC） was studied. X-ray diffraction pattern, scanning electron microscopy, energy dispersive spectrometer analysis and distribution maps showed that the phosphate iron particles surface layer contains a thin layer of nanocrystalline or amorphous phosphate with high coverage of powders surface. Magnetic measurements showed that the phosphated iron samples has excellent comprehensive electromagnetic properties. The phosphating process was carried out by stirring the iron powders in the solution with 0.01g/mL phosphoric acid concentration at room temperature for 30min. With increase in the phosphoric acid concentration, phosphating time or temperature, specific resistivity increases, magnetic loss decreases significantly at medium and high frequencies and permeability also decreased by some extent.%研究了磷化工艺对铁基软磁复合材料电磁性能的影响。

钝化工艺对软磁金属粉末钝化层影响的研究.
钝化工艺对软磁金属粉末钝化层影响的研究李伟健1，闫亮明1*，郭峰2摘要：通过不同PH值的磷酸溶液在不同温度下对气雾化铁粉进行了钝化，对所得的钝化粉末压制和热处理，得到了磁粉芯。
对其进行电磁学性质测试、SEM观察和盐雾试验。
结果表明，钝化过程中，金属粉末表面会形成磷化层从而达到钝化效果，并且反应溶液的PH值与反应温度对钝化效果都有重要的影响，反应温度升高、反应溶液PH值降低都有利于增强钝化效果。

School of Materials Science and Engineering, Innermongolia University of Technology, Huhhot010051；2. Kunshan Magenetic Flow New Material Technology Company, Suzhou 215300 , China)Abstract：Gas atomized ferrous powder was passivated by phosphoric acid solution with different PH value at various temperature. The magnetic particle core was made by suppressing and heat-treating passivated ferrous powder. The microstructure of the powder was analyzed by scanning electron microscope (SEM), the corrosion resistance of the powder was estimated by salt spray test and the eletromagnetic properties were test. The results show that the surface of the powder was passivated by forming a phosphating layer. The PH value and the reaction temperature of the solution have a significant influence on the passivation effect. The increase of temperature and the decrease of the PH value of the solution are beneficial to improve the passivation effect.Key word: Ferrous powder; deactivation; temperature; PH value1引言磁性材料应用于大量的电子、电气产品，是材料行业的基础之一[1]。

smc贴片封装流程
smc贴片封装流程The SMC (Surface Mount Component) packaging process is an essential part of electronic manufacturing. SMC packaging involves several steps to ensure the components are properly placed and secured onto the printed circuit board (PCB). 这个过程通常包括选取正确封装材料、制造封装模具、封装组装等多个步骤。
SMC packaging plays a crucial role in the overall performance and functionality of electronic devices.One of the most critical aspects of the SMC packaging process is the selection of the appropriate packaging material. The material used for SMC packaging should have properties such as thermal conductivity, electrical insulation, and mechanical strength. 同时，选用的封装材料还应符合环保要求，满足电子产品安全认证标准。
这确保了封装材料的可靠性和稳定性，有利于增强电子产品的使用寿命和性能。
In addition to material selection, the manufacturing of packaging molds is also a crucial step in the SMC packaging process. The molds are used to shape and form the packaging material into the desired shape and size. 制造高质量的封装模具需要精密的加工设备和技术，以确保封装材料能够准确地固定在PCB上。

新型各向异性稀土永磁材料产业化开发进展
新型各向异性稀土永磁材料产业化开发进展杨应昌北京大学物理学院应用磁学中心摘要本文重点讨论稀土-铁-氮各向异性新型永磁材料。
稀土－铁－氮永磁材料的化学通式为R x Fe y N z，R代表稀土元素。
它包括两类化学成分和晶体结构都不相同的材料：（1）Nd(Fe,M)12N x或Pr(Fe,M)12N x ，其中M= Ti、V、Mo等，具有ThMn12型四方晶体结构，这类材料通称钕铁氮；（2）Sm2Fe17N x ，具有 Th2Zn17型菱方晶体结构，简称钐铁氮。
稀土铁氮新材料产业化的优势是；（1）根据所发现的新效应而发明的新材料，其成分和结构都与现有的磁性材料不同，取得了包括美国、日本和欧洲等国内外发明专利；（2）开发了成熟的产业化技术，磁粉的最大磁能积高达40兆高奥，接近现有商品钕铁硼磁粉的3倍，但材料成本不足钕铁硼磁粉的三分之一；（3）产品已有明确的市场定位。
一、引言稀土永磁材料是稀土产业中的重要支柱。
稀土永磁材料的主导产品是钕铁硼，但是从当前技术发展的需求来看，钕铁硼有局限性，对钕铁硼要一分为二。
磁体有两类：烧结磁体和粘结磁体。
钕铁硼烧结磁体是各向异性的，并且是全密度磁体，所以磁性能是永磁之冠，应用日益广泛。
但是钕铁硼粘结磁体是各向同性的，电器小型化的发展趋势要求开发高磁能积的粘结磁体，日益凸显钕铁硼粘结磁体的不足：（1）性能局限性：磁粉是各向同性的，最大磁能积不过16兆高奥；（2）成型工艺的局限性：钕铁硼快淬磁粉主要用于制作压缩粘结磁体，其产量仅占总粘结磁体产量的3%，其它都是低性能的铁氧体粘结磁体。
而更广阔的粘结磁体市场如高性能注射磁体和柔性橡胶磁体亟待开发。
为了满足计算机、电机等产品的小型化和高性能化以及低碳经济的发展要求，开发和生产高性能的各向异性稀土粘结磁体是当前世界永磁材料领域开发前沿的生长点和竞争点。
此外，长期以来我国的稀土永磁材料产业的发展受到国外知识产权的制约，作为稀土资源大国，更需要争得先机、开发具有自主知识产权的各向异性稀土粘结磁体的新材料。
