Summary

The nature and mechanism of surface damage at ceramic interfaces are discussed using Si3N4 and SiC as examples. A test apparatus and approach are described that provide friction and strength degradation data as a function of load, temperature, contact geometry, and other variables. Experimental and analytical data are compared for 1976 reaction-bonded Si3N4 (RBSN) materials, improved 1980 RBSN, and sintered silicon carbide.
