摘　　要：研究了用复合电沉积法制备的颗粒增强Al2O3／Cu复合材料在10～100N载荷下和0．5～5m／s滑动速度下的耐磨性能及其磨损机制。结果表明，随载荷增加，磨损率升高存在一临界值，在中载时，随滑动速度升高，磨损率在3～4m／s时出现极小值，不同速度载荷时，表现出不同的磨损机制。The wearability and wear mechanism of Al2O3 comoposite prepared by electrodeposit method have beeninvestigated in case of 10~100N load and 0. 5 ~ 5m/s sliding speed. The results showed that the specific wearabilityincreasing with the increasing load in the range of 20~ 80N. It occurred minimal value at 3~4m/s when the slidingspeed increased. It occurred different wear mechanism at different speeds and under different loads.
