中文摘要：

将超高分子量聚乙烯（UHMWPE）与GCrl5轴承钢配副，研究了此摩擦副在H2（），溶液和去离子水中的摩擦磨损性能，分析了H2O2质量分数和载荷对其摩擦磨损性能的影响及其磨损机理。结果表明：UHMwPE／GCrl5配副在去离子水中的摩擦因数最大，同时，摩擦因数随H2O2质量分数的升高而增大；UHMWPE在去离子水、30％H：02、60％H2O2和90％H2O2溶液中的磨损体积分别为0．057，0．042，0．049，0．110mm3；配副在90％H202中的摩擦因数以及UH—MWPE的磨损体积和磨损面积均随着载荷的增大而增大；UHMWPE的磨损机制以磨粒磨损和弹塑性变形磨损为主，兼有氧化磨损。

英文摘要：

The friction and wear properties of ultrahigh molecule weight polyethylene（UHMWPE） couple with bearing steel GCrlS in hydrogen peroxide （H2 O2 ） solution and deionized water were studied, and the effects of the mass fraction of hydrogen peroxide and load on the tribological properties were studied. The results show that the friction coefficient of UHMWPE/GCr15 in deionized water was the highest, and the friction coefficient increased with the increase of the mass fraction of hydrogen peroxide. The wear volume of UHMWPE in deionized water, 30%HEO2, 60% HeO2, and 90%H2O2 were 0. 057, 0. 042, 0. 049 and 0. 110 mm3 , respectively. The friction coefficient of UHMWPE/GCr15 and the wear volume and wear area of UHMWPE increased with the increase of the load. The wear mechanism was mainly abrasive and plastic deformation wear with oxidative wear.
