锡锌合金是良好的防护性镀层,典型的合金组成为含锌25%左右。本文采用钼酸盐钝化处理,可进一步提高合金的耐蚀性;用AES和XPS方法对钝化膜进行了分析,并对钝化膜的性质和耐磨性进行了讨论。
Tin-zinc alloy is a good protective coating, the typical alloy composition is about 25% zinc. In this paper, molybdate passivation treatment can further improve the corrosion resistance of the alloy; AES and XPS methods were used to analyze the passivation film, and passivation film properties and wear resistance were discussed.
