Abstract

Thrust bearing tests were carried out under water lubrication with hot pressed Sialon, ZrO2 and Al2O3 fine ceramics. The life of Sialon balls mating with Sialon races was the highest, and it was reduced when mating with ZrO2 or Al2O3 races. The lives of ZrO2 balls and Al2O3 balls mating with Sialon races were longer than those of their self-mated contact. The friction coefficient of thrust bearings consisting of Sialon balls and/or races was comparatively small. The amount of wear of balls or races mating with Sialon was small, while that of Sialon mating with ZrO2 or Al2O3 was large. The main failure modes of Sialon balls were flaking in the case mating with Sialon races, and wear in the cases mating with ZrO2 and Al2O3 races. Those of ZrO2 and Al2O3 balls were wear with micro-flaking, and wear, respectively.
