一、引言镍-镉合金镀层,是一种中温防护镀层,它在500℃以下的环境中工作具有较好的防护能力。据文献报导,扩散的镍-镉合金镀层在国外五十年代已开始被采用,至于从槽中直接沉积镍-镉合金当前国外尚在探索,据文献报导,试验室研究已获得成功。采用扩散的镍-镉合金镀层,即要在镀的工作上,先镀一层结合力好,应力低的一定厚
I. INTRODUCTION Nickel-cadmium alloy coating is a kind of medium temperature protective coating. It works well in the environment below 500 ℃ and has better protection ability. According to the literature, diffused nickel-cadmium alloy coating has been used in foreign countries since the 1950s. As for the direct deposition of nickel-cadmium alloy from the groove, it is still being explored abroad. According to the literature, laboratory research has been successful. The use of diffusion of nickel - cadmium alloy coating, that is to be plated on the work, first coated with a layer of good bonding strength, low stress, a certain thickness
