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。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.
