Abstract
a-C:HMe coatings were deposited by cathodic vacuum arc evaporation. Selected mechanical and tribological properties of the a-C:HMe coatings are presented. It is shown that the coatings exhibit a low solid-state friction, a high seizure load and a high wear resistance. Their functional behaviour was investigated for both dry and lubricated friction couples. Beside the results achieved by laboratory model tests, tests of components from socket joints, hydraulic cylinders and hydraulic piston pumps are also presented. The present investigations indicate that the a-C:HMe coatings have a high application potential in fluid power transmission systems and in dry friction couples.
