Friction and wear behaviors of PEEK composite material in contaminated oil containing white-fused alumina particles were studied. For the comparison, white metal and un-filled PEEK material were also studied. Wear debris and worn surfaces were observed with a scanning electron microscope (SEM) and the wear mechanism was discussed. It was found that only large contaminant had the evil influence on the friction and wear behaviors for all tested materials. The friction coefficient for the PEEK materials became much higher than that for the white metal. On the worn surfaces of the PEEK materials, clear evidences showing cutting action due to sliding and rolling of contaminant were commonly observed. In contrast, on the white metal, long and continuous plowing grooves probably caused by sliding of contaminant were commonly observed.
