在含稀土镀铬添加剂的镀铬液中脉冲镀硬铬

Pulse Hard Chromium Plating with Additive Containing RE

在含有稀土镀铬添加剂的镀铬液中采用脉冲电镀工艺镀硬铬，能够大大提高沉积速度，镀层具有微裂纹结构，其硬度较直流镀有明显提高。

The effect of RE containing additive on pulse hardchromium plating was studied. It was shown that thedeposition speed could be greatly quickened with theRE additive addition, and the coating hardness wasobviously increased.
