一.氰化物电镀有它独到的优点,即镀层均匀、光亮、结晶细致、与基体金属结合力良好等。对于镀铜也是如此。但是氰化物是一种极毒的物质。对操作工人的身体健康极为有害,为了解决这个问题,我厂曾用多种配方进行过无氰镀铜的试验,但效果都不好,特别是镀铜层与基体金属的结合强度问题,一直未能得到满意的结果,不能满足生 1. Cyanide plating has its own unique advantages, namely coating uniform, bright, crystal and meticulous, and the substrate metal bonding strength is good. The same is true for copper plating. But cyanide is a very toxic substance. The operation of the health of workers is extremely harmful to solve this problem, our factory has used a variety of formulations for non-cyanide copper test, but the effect is not good, especially the copper layer and the base metal bonding strength has been Failure to get satisfactory results can not satisfy students
