摘　　要：化学镀镍层起泡脱皮会导致无镀层部位的加速腐蚀,在表面处理中是不允许出现的。因此,分析化学镀镍层起泡脱皮原因,找出其解决办法。通过试验得出结论:化学镀镍层有渗氢现象,原子态氢集聚形成气泡。减少施镀时间,降低镀层厚度,解决了镀层起泡脱皮质量问题,保证了化学镀镍零件的防腐性能。Bubbling and peeling on chemical nickel coating cause fast erosion of no coating part. The appearance can ＇ t. emerge in the surface treatment. In order to find out solving methods, reason of the bubbling and peeling on chemical nickel coating was analyzed. The research results show that hydrogen permeation reacts on the chemical nickel coating, and hydrogen-atom gathers to form bubble. Reducing plating time and coating thickness can solve these problems. So these methods can solve quality problem of the bubbling and peeling on nickel coating, and guarantee the preservative performance of the chemical nickelplating parts.
