Summary

Scuffing, described as a sudden catastrophic failure of sliding surfaces under severe contact conditions, is usually indicated by a sudden rise in friction, contact temperature and noise. In metals, scuffing occurs by a severe plastic deformation process. In the present study, we evaluated the occurrence of scuffing in four single–crystal ceramic materials namely, MgO, YAG, sapphire and cubic zirconia. Scuffing tests were conducted with standard blockon–ring test rig and lubricated with basestock Poly–alpha–olefin (PAO) synthetic lubricant. Single–event scuffing analogous to that observed in most metals was observed in MgO and YAG, while the sapphire and cubic zirconia exhibited micro–scuffing prior to scuffing failure. Scuffing in ceramics involves both plasticity and fracture.
