Femoral ball heads of aluminium oxide or zirconium oxide ceramics are used for total hip replacement. This application is based on their attractive tribological properties. Standard and state-of-the-art are femoral ball heads made of alumina (Al2O3) articulating against acetabular cups of polyethylene (PE-UHMW) and zirconia (Y-TZP) heads articulating against polyethylene cups. A very attractive wear couple is ceramic-on-ceramic. Some of the various ceramic combinations have been tested using the ring-on-disc method according to ISO 6474. The combination alumina/alumina was found to produce extremely low wear; catastrophic wear was found for the combinations alumina/Y-TZP and Y-TZP/Y-TZP.
氧化铝或氧化锆陶瓷制成的股骨头用于全髋关节置换。这种应用基于它们吸引人的摩擦学特性。标准的和最先进的是由氧化铝（Al2O3）制成的股骨头与超高分子量聚乙烯（PE-UHMW）髋臼杯相磨合，以及氧化锆（Y-TZP）股骨头与聚乙烯杯相磨合。一种非常吸引人的耐磨配对是陶瓷对陶瓷。已经根据ISO 6474使用环盘法对一些不同的陶瓷组合进行了测试。发现氧化铝/氧化铝组合产生的磨损极低；而氧化铝/Y-TZP和Y-TZP/Y-TZP组合则出现灾难性磨损。
