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.
