Thus far, seif-mated pin-on-disk siiding wear tests have been carried out with RBSN, HSN, and SSC materials. The tests were performed at a velocity of 0.1 m/s with a 1 kg static load in air at room temperature and a total sliding distance of 1000 meters. Tabie 4 summarizes the friction results obtained. The breakaway friction coefficients were measured prior to wear testing on surfaces polished to a 1 )xm finish. The values reported for the kinetic friction coefficients are the steady state values obtained after 500 meters of sliding. The microstructure, fracture surface, and reactions at the wear interface are currently being studied to provide more insight into the wear behavior of these ceramics.
