ABSTRACT
Wear is a complex phenomenon. Complication arises because of the many factors that aµect the wear processes coupled with the changing conditions at the interface during service and the formation of reaction products. Sometimes there are multiple wear mechanisms in play. ˜ese problems have made it di²cult to develop mathematical relationships that could be applied in designing for wear. ˜e practical approach involves using proper materials, controlling the environment, and changing the operating conditions so as to reduce the severity of anticipated wear.
