analysis is used to study the wear mechanism of the worn out surface. It is observed that as the sliding speed increases, the frictional heat also increases between the contact surfaces. The formed... that is associated with this wear mechanism. As sliding speed was raised, frictional heating led to a gradual softening of the pin surface, and thus, more extensive adhesion between pin and disc. ......
