摘要： 研究了O′－Sialon－ZrO2－SiC复合材料在室温和600℃的摩擦磨损行为．研究表明，在实验条件下，O′－Sialon－ZrO2－SiC复合材料的磨损率远低于不锈钢的磨损率，O′-Sialon-ZrO2－SiC／不锈钢摩擦副间的磨损机制主要是粘着磨损．分形结果研究表明，分形维数与磨损存在对应关系，即分形维数越大，材料磨损越严重．复合材料磨损界面的分形维数在1．26～1．38之间．

Abstract: The friction and wear properties of O -Sialon-ZrO2-SiC composite were studied at room temperature and 600℃. Results show that the wear rate of O -Sialon-ZrO2-SiC is much less than that of stainless steel at the testing condition, and main wear mechanism of the unlubricated friction is adhesive wear. It also indicates that the fractals dimension is related to the abrasion,the farger the fractals dimension, the greater the abrasion, the fractals dimension of wear ranges from 1.26 to 1.38.

Key words: O -Sialon-ZrO2-SiC, adhesive wear, fractals dimension
