镀铬工艺及其研究进展

镀铬工业在世界电镀行业中占据着举足轻重的地位,好的镀铬层具有很好的耐磨性和化学稳定性,可以长久裸露在空气中而保持颜色光泽不变。文章介绍了六价铬电镀和三价铬电镀工艺的优缺点以及一些代铬镀层的组成和特点;指出三价铬电镀工艺将会取代六价铬电镀工艺成为镀铬工艺的主体,应加大力度进行三价铬电镀工艺的研究。

Chromium Electroplating and Its Research Development

Chromium planting has important position in world electroplating field.Good chromium planting layer has good resistant and chemical stability,which could keep color and brightness in air longer.This paper introduced the advantages and disadvantages of chromium planting of Cr3 and Cr6 ,and some construction and characters of substitution chromium deposit.It was pointed out that chromium planting of Cr3 would instead the Cr6 ,and became the main chromium planting technology.Therefore,the research on chromium planting of Cr3 should be largely developed.
