Tribochemical wear of carbon films in oxygen

An experimental study of the desorption of sputtered carbon films to examine whether tribochemical processes activate the desorption reaction shows that tribochemical wear process induces desorption of carbon films to CO2 and CO surface oxides. The production of carbon dioxide during sliding in dry-oxygen and -nitrogen environments supports the tribochemical wear-induced desorption. The tribochemical wear model helps develop a sampling system and pressure interface for experiments.
