The role of oxygen in lubricated wear is discussed. Previous studies have shown that at low concentrations, oxygen can reduce wear, but at higher concentrations, it can increase wear. The situation is complicated by ZDTP antioxidants. The present paper reports experimental work aimed at elucidating the role of hydroperoxides ‐ whether they participate in the formation of wear‐resistant oxide films, if they (or peroxy radicals) are the main source of oxygen, and whether ZDTP‐hydroperoxide interactions in the wear zone are important in controlling wear.
