| Abstract: |
| Chromium electroplating is always carried out in a plating bath containing hexavalent chromium. Recently, since hexavalent chromium has bad effects on environment, etc. , research on the trivalent chromium plating has been accelerated. The trivalent chromium plating has been proposed for a long time. Trivalent chromium plating has some distinct advantages over hexavalent chrome on decorative application. There are potential problems on its application, and its available condition is limited. Thus, hard chromium plating has not yet been practically used. The mechanisms and prospect of trivalent chromium plating were introduced. And some problems that should be deeply studied were pointed out. |
