美国军方标准MIL-A-8625

MIL-A-8625E3.3.1.2 复杂工件阳极氧化:对形状复杂的工件进行阳极氧化时,电解质可能包埋工件孔穴。

所以,如采用本工艺,则须确保不会因电解质包埋而引发后续损伤(除指定特定镀层外,应采用I类或IA类镀层)。

3.3.2 处置及清洗应在前处理、阳极氧化及后处理中处置工件,以避免机械损耗及污染。

工件上不得有任何杂质、氧化物或土,包括:油脂、油污、涂料及助焊剂。

应采取适当清洗工序去除工件表面的氧化层及其它干扰层,以确保表面清洁且无水膜残痕。

因为磨料中含有铁、钢丝棉、粗糙的铁氧化物及钢线,这些物质都可能嵌进金属,加速铝及其合金的腐蚀,故阳极氧化前禁止采取机械清洗。

如要求进行特定清洗,则应在合同或订单中表明(见6.2)。

3.3.3 镜面表面处理如合同或订单中已指定(见6.2),则需在阳极氧化前将需要取得高反射性表面的工件进行化学或电化学光亮处理(见6.9)。

3.3.4 修整(机械损耗、接触痕)除非另有规定,否则任何机械损耗区域(阳极氧化层磨损,但未伤及工件的区域)应采用化学转化材料(参见1A类镀层QPL-81760)及其它可实施的方法进行修整。

本修整条例只适用于不慎导致的机械损伤,如划痕。

针对III类镀层,只能对后期不会遭受研磨的区域进行修整(见6.1.1)。

受损区域应小于总阳极氧化面积5%,否则不予整修。

如在合同或订单中有明确规定(见6.2),可采用上述用于修整机械损伤的方法来修整接触痕。

3.4 镀层正如合同、订单及可实施提款中所指定,可通过任何工艺或操作在铝和铝合金表面形成特定膜,以制得传统阳极氧化层。

3.5 I、IB和IC类镀层I和IB类镀层:在含有铬酸的槽液中电解处理铝和铝合金,从而在金属表面生成均一阳极氧化膜。

IC类镀层:在含有矿物质或含有矿物质和有机酸混合物(不含铬酸)的槽液中电解处理铝和铝合金,从而在金属表面生成均一的阳极氧化膜。

除非在合同、订单或可实施的条款中已明确,否则,不得采用标定铜含量>5%,或标定硅含量>7%,或标定合金成分的总含量>7.5%的铝合金来制取I类镀层。

Questions pertinent to this effectshall be referred by the contracting activity to the appropriate departmental medical service who will act as an advisor to the contracting agency.73.11 Painting/coating. Painting/coating operations shall be performed as soon as practical after the anodizing process on clean coatings. If parts require storage prior to painting/coating, they shall be stored in a manner that will avoid contamination. If the parts become contaminated, they shall be cleanedin a manner that will not be detrimental to the anodic coating or the basis metal, (see 6.3).3.12 Dyeing or coloring. Anodic coatings shall not be allowed to dry before dyeing or coloring. Items to be dyed or colored should be preferably coated by the Type II anodizing treatment (see 6.12). Dyed or colored coatings shall not be allowed to remain in rinse waters for more than 5 minutes before sealing.3.13 Workmanship. Except for touch up areas in accordance with 3.3.4 and as noted below, the applied anodic coating shall be continuous, smooth, adherent, uniform in appearance, free from powdery areas, loose films, breaks, scratches and other defects which will reduce the serviceability of anodized parts or assemblies. Differences in anodic coating appearance resulting from inherent base metal differences in a component such as the presence of welds, components containing cast and machined surfaces, and differences in grain size within a forging shall not be cause to reject the anodic coating unless otherwise specified in the contract or purchase order (see 6.2). Slight discolorationfrom dripping or rundown of the sealing solution from designed crevices in a component shall be allowed.3.13.1 Contact marks. The size and number of contact marks shall be at a minimum consistent with good practice (see 6.14). If a specific location for contact marks is desired, the location shall be specified on the contract or purchase order (see 6.2).4. QUALITY ASSURANCE PROVISIONS4.1 Responsibility for inspection.
