The initial energy of electrons injected into the plasma was 0,1 – 0,7 keV, energy of ions bombarding the coating was 0,1 – 0,7 keV and the pressure of Ar + C2H2 gas mixture was 0,2 – 1 Pa. Microhardness and wear resistance of coatings were measured by methods of kinetic indentation and ball abrasion. The coatings with high microhardness (40 – 60 GPa) and high wear resistance were deposited on conditions that ion energy exceeded 300 eV. It was shown that coating’s microhardness and internal stresses in the coatings deposited on chamber walls could be reduced by concerted change of voltage accelerating injected electrons and bias voltage applied to samples placed into the plasma. This allows to avoid delamination of coating particles from the walls and to provide high quality coating on samples.
