Abstract: In the present paper a comparative study of innovative diamond coatings with included micro- and nano- sized particles are investigated. The coatings are sintered with high-heat treatment and high-tech WC-12Co coating, applied with supersonic jet plasma (HVOF process) for use under extreme operating conditions. The results for mass wear, the intensity of wear and wear resistance under the same dry friction modes on the surface of rigidly abrasive particles are obtained. It has been found out that the highest wear resistance has a coating with included micro-diamond particles, which is about one order of magnitude higher than the wear resistance of a coating with included nano-diamond particles. The WC-12Co wear resistance coating is 3–4 order of magnitude lower than the wear resistance of diamond coatings with included nano- and micro- sized particles.
