摘　　要：对不同工艺条件下获得的Ni－Fe－P／Al2O3复合镀层的显微硬度及其耐磨性进行了研究。结果表明，复合层的显微硬度和耐磨性随Al2O3复合量、镀液中NaH2PO2·H2O浓度、电流密度以及施镀温度的改变而变化。在改变工艺参数的过程中，复合镀层显微硬度比Ni－Fe－P电沉积层平均高约Hv100～160。Microhardness and wear resistance of Ni-Fe-P/A12O3 composite deposit obtained from different technological conditions are investigated. Results show microhardness and wear resistance of composite deposit change with content of A12O3, concentration of NaH2PO2·H2O in bath, c.d. and plating temperature. In changing technological parameters, microhardness in composite deposit is averagely about Hv100～160 higher than that of Ni-Fe-P one.
