the observation of friction surface and bending fractured surfaces by means of sem shows that wear failure mechanism of zta ceramics belongs to brittle fracture mechanism.

toughness and strength can be increased by means of martensite phase transformation in zro_2, therefore abrasive wear resistance of zta will be possibly improved.

利用ZrO2的马氏体相变，可望提高陶瓷的韧性和强度，故可望提高Al2O3基陶瓷的耐磨性。

fine grain, low porosity with uniformity microstructure, and the high hardness and high fracture toughness can improve the wear resistance of the zta composite materials.

显微结构以及硬度和断裂韧性共同影响ZTA复合材料磨擦磨损性能。晶粒细小均匀，气孔率低，晶间结合致密以及高硬度和高断裂韧性均能提高复合材料的耐磨性能。

therefore, the removal mechanism of no-elastic deformation in ultrasonic elliptic vibration grinding of zta ceramics had important influence on the surface integrity.

普通磨削和超声椭圆振动磨削的表面上都观察不到非晶相。试验结果表明，ZTA的非弹性变形去除对表面完整性有重要影响。

based on the design of compound microstructure and complex strengthened toughness, al2o3 and zta ceramics were prepared using self-made ultrafine powders.
