Abstract—Wear is defined as a set of adhesion, transfer, abrasion, fatigue and oxidation. Due to these processes transfer of matter takes place from one state to another. The final transformation in wear is a collection of free debris particles. Oxidation is a wear of metals in which oxide layer is formed. Oxidation rate is inversely dependent on the thickness of oxide layer. Mechanical characterstics of oxide layer is the basic factor in determining the wear process. Theoretically it can be shown that oxidation temperature is lower than the contact temperature at the contact regions. Also the oxidation rate may decrease with the increasing oxidation temperature because of increase in thickness of oxide layer
