铝合金上电镀新工艺

A New Pretreatment Process for Cr-Ni Electroplating on Al Alloys

提出了在含有镍盐的电解液中,用10～15V、50Hz的交流电对铝合金处理5～10min的新工艺,再在处理后的铝合金上电镀Ni、Cu等,可以获得结合力很好的镀层。

A new process of pretreating aluminium alloys in nickel salt solutions for 5～10 minutes, with 50 Hz alternating current, voltage ranging from 10～15V, is reported. The adhe sive between aluminium substrate and the coatings is favourable.
