A study of diamond-like carbon coatings deposition has been carried out. The coatings were deposited on ceramic cutting tools. Vacuum-arc plasma has been used for deposition. Dependencies of the coatings microhardness and density on the tools bias voltage U are presented. The microhardness reaches 50 GPa at U=100 V. With increasing U and temperature it decreases to 15 GPa at U=500 V. Effect of the coatings on oxide ceramics properties was revealed. They were used for lathe turning of hardened steel. The tests proved a high efficiency of the coatings.

Diamond-like carbon (DLC) films are deposited by bend filtered cathodic vacuum arc (FCVA) technique with DC and pulsed bias voltage. The effects of varying bias voltage on nanoindentation and nanowear properties were evaluated by atomic force microscopy. DLC films deposited with DC bias voltage of −50 V exhibited the greatest hardness at approximately 50 GPa, a low modulus of dissipation, low elastic modulus to nanoindentation hardness ratio, and high nanowear resistance. Nanoindentation hardness was positively correlated with the Raman peak ratioId/Ig, whereas wear depth was negatively correlated with this ratio. These nanotribological properties highly depend on the films’ nanostructures. The tribological properties of the FCVA-DLC films were also investigated using a ball-on-disk test. The average friction coefficient of DLC films deposited with DC bias voltage was lower than that of DLC films deposited with pulse bias voltage. The friction coefficient calculated from the ball-on-disk test was correlated with the nanoindentation hardness in dry conditions. However, under boundary lubrication conditions, the friction coefficient and specific wear rate had little correlation with nanoindentation hardness, and wear behavior seemed to be influenced by other factors such as adhesion strength between the film and substrate.
