化学镀镍-磷液的周期循环研究

A Cyclical Research on Electroless Ni-P Bath

采用中磷配方进行周期循环 (MTO)实验 ,研究镀液的维护与补充方法。实验发现 ,随着镀液老化 ,镀速下降 ,镀层中磷含量则比较稳定 ,pH值对镀液有很大的影响。

The bath maintaining and making up method is researched via MTO experiment using MP bath. The results show that with the aging of the bath, the doposition speed is declined, but the P content in the plating coating is more stable; pH value has a great influence on the bath. The make up process resulted from the experiment can be directly used into production.
