Effect of environment on the tribological behavior of Si-incorporated diamond-like carbon films
초록
An experimental study was performed to discover the effect of environment on the tribological behavior of Si-incorporated diamond-like carbon(Si-DLC) film slid on a steel ball. The films were deposited on Si(100) wafers from radio-frequency glow discharge of mixtures of benzene and dilute silane gases. Experiments using a ball-on-disk test-rig was performed under vacuum, dry air and ambient air conditions. It was observed that coefficient of friction was decreased as the environmental condition changes from vacuum, to dry air. It was also observed that the coefficient of friction decreased with increasing silicon concentration in the film. Chemical analyses of debris suggested that the low and stable friction coefficient is closely related to the silicon rich oxide debris and the rolling action.
