三价铬盐镀液电镀硬铬镀层的性能

Properties of Hard Chromium Plating in Trihydric Chromate Bath

摘要: 用三价铬盐溶液电镀出了>70μm的硬铬镀层,研究了镀层的性能。镀层是非晶态,含碳量4%左右,经过热处理后其硬度达到1600Hv以上。

Abstract: The properties of hard chromium plating in trihydric chromate bath has been studied. The content of carbon in the plating is about 4%, and the plating is noncrystalline. After the plating is heat treated, its Vickers hardness more then 1600.
