Abstract: To take alumina ceramics as researching object, using experimental method, illustrates the preparation process of alumina ceramics, researches the influence factors to friction and wear feature of alumina ceramics including additive concentration, sintering temperature, loading weight, speed of rotation.The study results showed that the wear rate of ceramics was low. In industrial products, the ceramics as wear-resistant material has a good prospect.

Key words: alumina ceramics, friction and wear, microstructure, friction coefficient
