摘　　要：铝及铝合金性质活泼 ,需经预处理才能进行电镀。采取二次浸锌的方法 ,在铝合金表面形成了一层锌层 ,再电镀暗镍、亮铜及装饰铬 ,得到了质量较高的镀层 。Aluminum and aluminum alloys are both reactive metals so that they need pretreatment before electroplating. The present work took methods of immersing the alluminum alloy into zinc solution two times, and formed a zinc layer on the aluminum alloy surface. Afterwards, dark nickel, bright copper and decorating chromium could be electroplated and plating films of good properties were obtained.
