摘　　要：研究了用做人工关节材料的一种ＺｒＯ２增韧陶瓷Ｃｅ－ＴＺＰ陶瓷，藉以进一步研制性能优于其它陶瓷的人工关节。用ＸＲＤ、ＳＥＭ、ＯＭ分析了材料的矿物组成和微观结构。测定了材料的性能，结果表明：在１６５０℃烧成的１２ｍｏｌ％Ｃｅ－ＴＺＰ陶瓷材料性能最佳，断裂韧性为１１．１１８０ＭＰａ·ｍ１／２，抗弯强度为５１２．９５ＭＰａ。初步探讨了材料的成分、烧成温度、微观结构与性能的关系。本文还研究了用于Ｃｅ－ＴＺＰ陶瓷人工关节柄部的Ｚ－Ｈ多孔涂层材料。The paper reports the artificial joint,an strengthening tenacity ceramic with ZrO 2——Ce TZP ceramic,then the author has manufactured the artificial joint superior in performance to other ceramics,and determined material composition of mineral,microcosmic structure and performance with XRD,SEM.The results show:Ce TZP ceramic,after fired in 1650 ℃,has shown the best performance with breaking tenacity of 11.1180 MPa·m 1/2 ,bending strength of 512.95 MPa. At last the author initially discusses the material components,firing temperature,microcosmic structure relating to the material performance,and has studied the porous coating material on the surface of the Ce TZP ceramic artificial joint handle.
