摘要
作者总结数十年电镀实践经验,认为镀铬液的调整,也应采用赫尔槽试验。通过对硫酸铬酸比和三价铬的认真调整,能从不含添加剂的普通镀铬液获得宽的光亮电流密度范围;在经恰当活化处理的亮镍层上能实现低温套铬,节能效果显著。
Chromeplate liquid's adjust alse needs Hull trough test.Through the adjust of the vitriol-chrome-acid and trivalence chromic,can from the net contain additive common chromeplate liquid gain wide bright electric current density bound;carry out the low temperature cover chrome on the aptitude activation dispose bright nickel layer, saving energy effect notability.
