Abstract :
Tribological properties of Diamond Like Carbon coatings in hydrogen-free (Gl) and hydrogenated (Dl) forms were investigated. Coefficient of Friction (CoF) of both Gl and Dl was found to increase with normal load. For Gl, it was destruction of lubricious tribo-layers at high load while for Dl, it was the formation of active atomic sites passivating themselves by interacting with surface atoms present in the counter body.
