Abstract—Formation of oxide has a significant effect on friction and wear of high temperature alloys during reciprocating sliding in air. A smooth wear protective oxide layer is developed on the load bearing surface in these alloys above a certain temperature of 150-250 ºC. However at lower temperature the metal-metal contact is reduced due to the oxide debris which in turn reduces the friction and wear rate. Due to transient oxidation of metal surface, removal of such oxide and then reoxidation of exposed metal, the oxide debris is formed. Oxide debris develops a wear protective layer between the sliding surfaces. As limited asperity growth occurs before the asperity becomes sufficiently large hence the friction during sliding is less. This research paper covers the relation between the sliding wear of alloys and the effect of oxides on it
