The friction properties of hydrogenated amorphous carbon (a-C:H) films slid against SUJ2 and Si3N4 balls were investigated in the relative humidity of 10-75%. Although it is usually said that the a-C:H films show low friction coefficient and high wear resistance, the friction properties vary according to their microstructure and the relative humidity in the environment. To investigate their effects on the friction, first, Raman spectroscopy was conducted to classify the microstructure of a-C:H films, and the water adsorption properties of a:C:H films were measured using quartz crystal microbalance. The friction results were shown from the microstructural view, and the role of water adsorption layers on friction properties were discussed.
