Severe Environment Testing of Silicon Nitride Rolling Elements.

Abstract

Wear rates for dry film lubricated rolling-spinning contacts of silicon nitride surfaces were studied to 540 C wear rate was essentially constant to 315 C. Surface stress modifications in hot pressed silicon nitride have been shown to improve tensile stress behavior under high magnitude Hertzian stress fields. (Author)
