摘要:
介绍了一种镀层镍含量为12%～15%的碱性镀锌-镍合金工艺，并将经过三价铬钝化的锌-镍镀层与六价铬钝化的镀镉和镀镉-钛层的外观、结合力、耐蚀性及氢脆性等进行对比。结果表明：锌-镍合金镀层的耐蚀性能优于镀镉层和镀镉-钛层，氢脆性合格。且该工艺环保低污染，能够替代镀镉、镀镉-钛用于起落架钢零件的表面防护。
Abstract:
An alkaline zinc-nickel alloy coating with nickel content of 12%-15% is introduced. The appearance, adhesion, corrosion resistance and hydrogen embrittlement of zinc-nickel coating passivated by trivalent chromium are compared with those of cadmium plating and cadmium-titanium plating coating passivated by hexavalent chromium. The results shows that the corrosion resistance properties of zinc-nickel alloy coating are better than those of cadmium plating and cadmium-titanium plating coating , and the hydrogen embrittlement of zinc-nickel alloy coating is qualified. The process is environmental protection and low pollution, and can replace cadmium plating and cadmium-titanium plating for surface protection of landing gear steel parts.
