摘　　要：为了探索ＳｉＡｌＯＮ陶瓷与超高分子量聚乙烯（ＵＮＭＷ－ＰＥ）组合作为人工关节置换材料的可能性，利用Ｆａｌｅｘ摩擦磨损实验机测定了ＳｉＡｌＯＮ陶瓷与ＵＨＭＷＰＥ在３７℃、血浆润滑条件下的生物摩擦学性能。同时，在扫描电镜下观察了摩擦副表面形貌。实验结果表明ＵＨＭＷＰＥ－ＳｉＡｌＯＮ陶瓷摩擦副的摩擦系数为０．０６，ＵＨＭＷＰＥ的磨损系数小于８．４５×１０－１０ｍｍ３／（Ｎ·ｍ）。表面轮廓仪对摩擦磨损前后ＳｉＡｌＯＮ陶瓷表面测试，未发现明显变化，说明陶瓷磨损甚微。根据ＸＰＳ分析结果，提出了生物摩擦磨损机理。The biological friction and wear properties of UHMWPE rubbing against SiAlON ceramics lubricated with plasma were evaluated using Falex at 37,and the surfaces of specimen were observed with SEM and surface profilmeter.The results indicated that the friction coefficient of UHMWPE-SiC was about 0.06.the wear factor of UHMWPE was lower than 8.4510-10mm3/(Nm),and the wear loss of SiAlON ceramics was very small.Based on the results of XPS analysis,the mechanism was proposed.
