摘　　要：采用正交设计法对Ni P/Al2 O3 化学复合镀工艺进行了优化。研究了镀液成分、工艺参数对复合镀层厚度、显微硬度、耐蚀性、耐磨性的影响。结果表明 ,Ni P/Al2 O3 化学复合镀层的显微硬度、耐磨性优于Ni P化学镀层的 ,弥散分布的Al2 O3 颗粒能显著减缓复合镀层在较高温度下的软化趋势。The process of electroless plating Ni P/Al 2O 3 composite coating was optimized by orthogonal experiment.Effects of plating liquid composites and process parameters on the thickness,microhardness,corrosion resis tance and wear resistance of the Ni P/Al 2O 3 composite coatings were studied.The results show that the micro hardness and wear resistance of the Ni P/Al 2O 3 composite coating are better than those of Ni P chemical coating.The Al 2O 3 grains distribution in dispersion can slow down the soften rate of the composite coatings significantly in high temperature.
