TERNARY ANTIFRICTION LAYERS OF C-TI-ME () TYPE AND DEPOSITION METHOD

The invention relates to ternary antifriction layers of C -Ti-Me type, where Me may be Ag or Al, which are used to coat the mechanical elements made of metals or metallic alloys for minimizing the dry friction coefficient for improving their resistance to fatigue and wear, and also to a method of depositing the same. According to the invention, the antifriction layer consists of a carbon-titanium film doped with metallic inclusions of Ag or Al, the film thickness ranging between 0.5...1.5 μm with sp3, sp2 and sp1 bonds, in which the concentration of the bonds sp3>20%, the friction coefficient is within the range of 0.2...0.6, and hardness is 20±5 GPa. The claimed method is based on the vacuum deposition, by means of thermionic arc, of the pure raw materials of graphite, titanium, silver, aluminium, processed in high vacuum < 5 x 10 without the use of any gas for achieving the plasma state.
