摘要
通过化学镀方式在经过清洗、粗化、活化的硬质合金表面镀覆了Ni/Co-P-Ag涂层。通过观察涂层的组织形貌,测试涂层的物理化学性能的方法研究了不同预处理工艺对化学镀Ag的影响,得到最佳的化学镀Co-P-Ag预处理方案。经过大量实验研究发现,通过预镀钴不仅能得到均匀的镀银涂层,化学镀Ag层还具备较好的结合力。
Ni/Co-P-Ag alloy film was deposited on the surface of cermet by electroless plating after cleaning, roughening and activation. Study the effects of different ways of Ag plating pretreatment by seeing the morphology of coating and testing the physical and chemical properties of coating, and the best Co-P-Ag plating pretreatment was obtained. Through large numbers of tests, we found that having a pre-cobalt layer before silver-plating could get a uniform coating, and the electroless silver plating layer has a forceful adhesion of the silver to the basis metal.
