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
