摘　　要：研究了化学镀锡溶液组成和工艺条件对镀层表面形貌的影响。结果表明,主盐、配位剂、表面活性剂和光亮剂对化学镀锡层的形貌影响较大。而且镀层中粒子随着施镀时间的延长和温度的提高逐渐增大,同时溶液的pH值,以及还原剂等对镀层的表面形貌也有一定的影响。The effects of the composition and controlled conditions of eleetroless tin plating on the morphology of coatings are mvestigatecl. The results show that stannous salt, complexing agent, surfactant, and brightener have more impact on the morphology of electroless tin coatings. The tin particles in the coatings will become larger with the increase of plating time and temperature. And the morphology of tin coatings is also affected by pH and reducing agent.
