Objective of this program was to develop a theory to predict wear behavior of lubricated and unlubricated ceramics in sliding contact, and present it in a form useful for designers. It is assumed that the contact between bodies in sliding motion produces a stress field and frictional heat source that may induce severe wear from material yielding or fracture. A thermomechanical wear model is used to develop a wear transition equation for identifying the dominant factors that will reduce or control such wear by employing thermoelasticity analyses and contact mechanics. This equation is used to construct wear maps for ease of analysis. Studies are devoted to substantiating the thermomechanical wear model by using experimental results that emphasize the transition from mild to severe wear for dry and lubricated metallic and ceramic sliding contacts under load.
