Abstract: The friction behaviour of unlubricated contacts between a hydrogenated amorphous carbon coating and corundum counterbodies was investigated under reciprocating sliding conditions in ambient air. Tests were performed under various normal forces at controlled relative humidity. The coefficient of friction is shown to decrease as the normal contact force increases. At low (5%) and medium (50%) relative humidities, linear correlations between the coefficient of friction and the inverse of the hertzian contact pressure were observed. A physical interpretation for this behaviour is proposed by considering interfacial shear mechanisms accommodating the sliding motion.
