Dufrane, K F

The basic sliding behavior of ceramics for advanced heat engines is studied using a laboratory apparatus. The objective is to develop mathematical models of the wear processes based on experimental data. The apparatus evaluates the friction and wear behavior of ring and cylinder specimens at temperatures to 650 C under reciprocating conditions reproducing those of advanced heat engines. Dry sliding experiments with several plasma-sprayed ring materials and monolithic zirconias and alpha-silicon carbide were unsuccessful. High friction and high wear caused extensive surface damage. Lubricated sliding was successful with alpha-silicon carbide, but the zirconias had extensive surface damage due to thermoelastic instability.
