黑色金属零件表面电镀一层铜、镍、铬、锌等金属,可以达到抗蚀防锈和美观耐用的目的。但由于电镀过程要产生“三废”,污染环境,使电镀生产受到制约。因此某些非用于装饰而主要为了抗蚀防锈的零件,如仪器仪表、照相机、电视机、收录机等的内部零件,可以用抗蚀氮化来代替电镀。我们通过一年来的生产使用,感到其优越性十分显著。 Plating a layer of black metal parts on the surface of copper, nickel, chromium, zinc and other metals, can achieve the purpose of corrosion and rust and beautiful and durable. However, due to electroplating process to produce “three wastes”, polluting the environment, so that the production of electroplating is restricted. Therefore, some non-decorative and mainly for anti-corrosion rust parts, such as instruments, cameras, TVs, tape recorders and other internal parts, you can use corrosion nitriding instead of plating. Through the years of production and use, we feel that its superiority is very significant.
