摘 要: 先将铝合金样品阳极氧化30 min,然后电镀铜5 min,最后化学镀镍30 min,可以在铝合金表面获得颜色稳定、结合性能良好的复合层,且复合层致密,厚度可达20μm以上,复合层的硬度HV0.025/20达到450以上.阳极氧化和电镀铜所用溶液相同,给生产带来了方便. The composite coating was prepared on an aluminum alloy by anodizing,copper electroplating and chemical plating Ni-P.The microstructures and hardness of the surface layer were analyzed by using metallographic microscope and microhardness instrument,and the adhesion property of the composite coating was analyzed qualitatively.It is found that the hardness of composite coating is up to 450 HV_(0.025/20),and could gain a good combination of adhesion strength under certain conditions.
