以45~#和50~#碳钢为主体的某工件,过去的表面防锈一直采用工艺简便的发兰处理而获得黑色氧化膜保护层,但其耐磨耐腐蚀性能差,不能适应当前社会主义建设迅速发展的要求。为寻找一种耐磨耐腐蚀性能较好,工艺简便,而膜层仍呈黑色的新工艺,我们经过一年多的摸索,并在重庆建设机床厂、江津长风机械厂、五四研究所、武汉材料保护研究所等单位帮助下,找到一种黑色磷化工艺。所得黑色磷化膜保护层,经检查和实
To 45 ~ # and 50 ~ # carbon steel as the main part of a workpiece, the past, the surface rust has been using a simple process of hair blue treatment to obtain a black oxide film protective layer, but its poor wear and corrosion resistance, can not adapt to the current society The demand for the rapid development of the construction of doctrine. In order to find a new wear-resistant and corrosion resistance process is simple, and the film is still black new process, we have after more than a year of exploration, and in Chongqing Construction Machine Tool Plant, Jiangjin Changfeng Machinery Factory, May Fourth Research Institute Wuhan Institute of Materials Protection and other units to help find a black phosphating process. The resulting black phosphate coating protective layer, after checking and real
