摘要
研究了稀土添加剂对Ni—W—CO合金镀液性能及镀层性能的影响.实验结果表明,稀土添力。剂可提高镀液的电流效率、最大允许电流密度和阴极极化率,加速合金沉积,使镀层结晶颗粒细化、镀层硬度提高.
This paper deals with the effect of rare - earth additive on the properties of plating liquor and Ni-W-Co alloy coating. The resultshows that, rare - earth additive could increase current efficiency, maximum allowable current density and cathodic polarzation, rare earth additives play a role in accelerating alloy sedimentation, fining grains and moresing hard ness of the coating.
