Abstract
Ion-plasma antifriction coatings based on Ti-Cu were deposited by the method of ion-plasma sputtering in vacuum with the aim to gain a coating with a low coefficient of friction. To protect steel part from wear intermetallic, nitride and conglomerate coatings based on Ti-Cu with thickness of the coating h ≈ 2-5 μm obtained at different regimes of deposition. Thickness of the antifriction coatings and proportion of the chemical composition varied by deposition time, voltage and current of the magnetron, current of evaporators, pressure of gas in a vacuum chamber. This paper presents the results of the tribotest carried out on CSM Instruments pin-on-disk type tribometer. Comparing with uncoated samples microhardness and roughness of the coated samples increased two to three times, coefficient of friction of coated samples was twice lower.
