The role of atmospheres and lubricants in the oxidational wear of metals

The formation of oxides during wear is reported to reduce wear and friction of metals by preventing severe metal-to-metal contact. However, the oxides formed at the contact areas are not always effective in reducing the wear of metals. There are many factors that affect the formation of oxides at the contact areas. The effect of atmospheres is a key factor since it controls the oxidation kinetics and oxide morphology. The oxides are also formed under lubricated conditions. The effect of dissolved oxygen in the lubricants plays a very important role in the wear of metals. In this paper, the role of atmospheres and lubricants in the oxidational wear of metals is reviewed.
