Tribological Performance of Cr-Containing DLC FilmsDiamond-Like-Carbon films have been widely recognized as being a wear-resistant solid lubricant with a low friction coefficient. Recently, there have been many attempts to improve the tribological behavior of DLC films by the addition of various metals. In this study, in order to apply for severe sliding conditions, for example, for auto-motive parts, etc., tribological performance of Cr-containing DLC films has been investigated. Cr-containing DLC films were deposited by means of an ion-plating having electrical resist-heating unit for Cr vaporization. The reactive evaporation between C vapor using electron-beam and Cr vapor has been carried out under various plasma-gas conditions. DLC films were also prepared using same ion-plating for comparison. Tribological performances of the films were demonstrated by means of a ball-on-disk tribometer under various lubricating environments. Friction coefficient of Cr-DLC film is lower than that of DLC film under oil lubrication with appropriate additives.
