Abstract: A new kind of zirconia matrix ceramic material (ZrO₂/Al₂O₃) is developed with 3Y-PSZ(3% Y₂O₃ partially stabilized ZrO₂) and the additive of alumina. The wear resistance of ZYA20 (3Y-PSZ+20% Al₂O₃) is experimentally investigated comparing with ZYA30 (3Y-PSZ+30% Al₂O₃) by the wear ring-block test. It is shown that the friction coefficients of ZYA20 and ZYA30 decrease with the increment of the applied load and the wear ratios increase with the increment of the applied load. It is also found that their wear mechanisms are plastic deformation, adhesive and abrasive wear as well as stripping. The wear resistance of ZYA20 and ZYA30 is very good at low load and the former is stronger than the latter.
