电沉积Ｎｉ－Ｗ－Ｐ非晶合金中Ｗ含量可高达５５．２％，硬度为７００～１１００Ｈｖ，经５５０℃热处理，可达１３００～１４００Ｈｖ．镀层硬度和耐蚀性优于Ｎｉ－Ｐ非晶镀层［１］．非晶镀层中的类金属元素Ｐ可使腐蚀电位正移；高熔点元素Ｗ可使合金镀层在酸溶液中发生钝化，且Ｗ含量越高维钝电流密度越低；金属Ｃｒ元素除降低维钝电流密度外，还使钝化区范围加宽，孔蚀电位显著变正．浸泡实验结果表明，在３０℃、１ｍｏｌ／Ｌ的ＨＣｌ溶液中，不锈钢ＳＵＳ３０４的腐蚀速率为Ｎｉ－Ｗ－Ｐ非晶镀层的１０倍、Ｎｉ－Ｗ非晶镀层的４０倍和Ｆｅ－Ｗ非晶镀层的１５～５０倍．在６０℃、０．５ｍｏｌ／Ｌ的Ｈ２ＳＯ４溶液中，不锈钢的腐蚀速率为Ｆｅ－Ｗ非晶镀层的１８０倍、Ｎｉ基镀层的１００～７００倍．
Electrodeposition of Ni-W-P amorphous alloy W content up to 55.2%, the hardness of 700 ~ 1100Hv, 550 ℃ heat treatment, up to 1300 ~ 1400Hv. Coating hardness and corrosion resistance than Ni-P amorphous coating [1]. The metalloid P in the amorphous coating can make the corrosion potential shift positively. The high melting point element W can passivate the alloy coating in acid solution, and the higher the W content is, the lower the blunt current density is. Blunt current density, but also to widen the passivation area, the pitting potential significantly positive. The results of immersion experiments showed that the corrosion rate of stainless steel SUS304 was 10 times that of Ni-W-P amorphous coating, 40 times that of Ni-W amorphous coating and Fe-W amorphous Plating of 15 to 50 times. In 60 ℃, 0.5mol / L H2SO4 solution, stainless steel corrosion rate of Fe-W amorphous coating 180 times, Ni-based coating of 100 to 700 times.
