Abstract

The unlubricated sliding wear of an alumina-silicon carbide whisker composite (20 volume percent whiskers) was investigated in air at 20, 400, and 800degC. Severe wear began within the first kilometer of sliding at 400degC, while at 800degC mild wear resulted at stresses as great as 150 MPa. Auger analysis of the surface showed the wear track to be covered by a mixture of aluminium and silicon oxides and the exposed silicon carbide whisker surfaces to be oxidized.
