Friction coefficient of the deposited DLC layer as a function of the test ball material

DLC coatings have numerous properties that can be utilized in industry. Low coefficient of friction, hardness, abrasion resistance, and corrosion resistance are their principal advantages. Coatings are evaluated with a variety of test methods. The results of experiments, which are the subject of this paper, were conducted using the ball-on-flat method. The tribological pair was comprised of a plate with a DLC coating and a test balls composed of three different materials. The outputs of experiments are the friction coefficient curves as well as the optical evaluation of the wear of the DLC coating. In all three types of tested tribological pairs, the coating was worn, however there was no complete removal of the DLC coating from the plate. The level of coefficient of friction shows nearly constant values after run-in phase.
