摘　　要：用化学镀的方法制备了几种不同粒径的Ni-W-P／Al2O3复合镀层，研究了热处理温度对镀层硬度和磨损性能的影响，并将含有50nm、500nm、1～3μmAl2O3粒径的复合镀层进行了性能对比。结果表明：含有50nmAl2O3，粒径的复合镀层具有更高的硬度和耐磨性，经400℃处理后的镀层耐磨性最好。Ni-W-P/Al2O3 composite coatings were fabricated by electroless plating process. The influences of heat treatment temperature on the hardness and wear resistance of the coatings were investigated. Comparison study made on the composite coatings with 50 nm, 500 nm and 1- 3 μm Al2O3 particle size shows that both the hardness and wear resistance of Ni-W-P-50nmAl2O3 coating are higher than that of the others, which can reach maximum values when heat treated at 400 ℃.
