Dimigen and Huebsch discovered that carbon-rich metal/carbon coatings that are deposited with a process combining reactive magnetron sputtering with plasma activated chemical vapor deposition show promising tribological properties. We investigated some of these for metal/carbon compounds of chromium, tungsten, and titanium of different stoichiometry. Friction coefficients against high-carbon low-alloy steel were measured in a three pin-on-disk configuration. Three-body wear resistance was evaluated using a modification of the three pin-on-disk equipment, where a polishing powder suspension was fed continuously into the tribocontact. The results showed a strong dependence of the tribological properties on composition. The variation in the three-body wear resistance of tungsten carbon compounds agreed with Rabinowicz's model for the dependence on Vickers hardness.
