复合镀层技术开发使过去把镀层仅仅作为材料防护、装饰的应用范围向前推进了一大步。近年来,尤以 Ni-P 合金复合镀层在工程材料及功能材料等方面的应用,与表面镀硬铬,表面化学热处理,表面真空喷涂等相比,已初步显示其优越性。所谓 Ni-P 复合化学镀就是指用化学的方法将一种或几 The development of composite coating technology has made the use of coating as material protection in the past, and the application of decoration has taken a big step forward. In recent years, especially in Ni-P alloy composite coating in engineering materials and functional materials and other aspects of the application, and the surface hard chrome plating, surface chemical heat treatment, the surface of the vacuum spray compared to preliminary performance has been shown. The so-called Ni-P composite electroless plating refers to the chemical method will be one or a few
