MECHANISTIC STUDY OF THE EFFECTS OF ENVIRONMENTAL SPECIES ON THE FRICTION AND WEAR BEHAVIOR OF HIGHLY-HYDROGENATED DLC FILMS

摘要

The results of this study have confirmed that the friction behavior of hydrogenated DLC films used in this study is very sensitive to environmental oxygen and, counter-face material. The degree of graphitization was much higher when the counter-face material was steel. It is believed that, iron oxide that forms between sliding surfaces should be responsible for very high friction coefficient and wear in dry oxygen conditions.
