Ceramic Gas Bearing Material Evaluation

Abstract

Flat washer specimens were experimentally tested under conditions simulating start-stop and continuous rubbing contact of a gas-lubricated thrust bearing. Minimum surface damage with a constant and low value of the friction coefficient were criteria for judging superior PERFORMANCE. The materials tested consisted of conventional plasma-sprayed substrates (used as reference materials), solid silicon nitride, beryllium oxide, and beryllium both coated and uncoated.
