锌镍合金镀层的铬酸盐钝化

Chromate Passivation of Zn-Ni Alloy Plating

    摘要
  • 摘要: 采用一种新的铬酸盐钝化处理方法,可进一步提高含镍量为12%~13%的锌镍合金镀层的化学稳定性,其耐蚀性比未钝化的高5倍。研究了铬酸盐溶液成分及操作条件对钝化膜形成机理的影响,并对膜的耐蚀性与防护机理进行了探讨。

     

    Abstract: The chemical stability of Zn-Ni alloy coating containing 12%~13% Ni is further improved in this paper by means of a new chromation process and its corrosion resistance is five times higher than unchromation one.The effects of the composition of chromate solution and operation conditions on formed mechanism of conversion coating were investigated,and the protective mechanism of the coating was also discussed.
