镁及镁合金表面化学镀Ni-P合金新工艺

Electroless Ni-P Plating Technology for Magnesium and Its Alloy

通过多次试验确定了镁及镁合金的前处理方案 ,以磷酸洗的方法代替传统的铬酐加三氯化铁酸洗浸蚀的前处理工艺 ,配置简单 ,操作方便 ,以浸锌层、氰化铜层和中性镍层作为化学镀中间层 ,得到了结合力良好的化学镀镍层 。

Optimal pretreatment conditions of electroless nickel plating for magnesium were decided by many experiments. Phosphoric acid technology was used to instead of acid processing by chromium trioxide and ferric chloride, and excellent coating was obtained by using dipped zinc, cyanide copper, nickel as medium.
