Wear investigations on superhard amorphous carbon films

Mechanical-tribological investigations were performed on super-hard amorphous carbon films. These films were deposited by a high-current arc method. Films with a thickness up to several micrometers exhibit good adhesion and are suited for variuos wear protective applications. Beside measurements of adhesion class, roughness and Young's modulus oscillating sliding and rolling contact wear tests have been carried out. Several interrelationships between wear rates and different film properties and counter bodies of the wear tests, respectively, are pointed out.
