Abstract:
The features of the structure, phase composition and mechanical properties (nanohardness, Young's modulus, friction and wear
coefficients) of composite titanium-carbon coatings deposited by the ion-plasma method in a hydrocarbon gas atmosphere at
different pressures are considered. It was found that carbon titanium-containing coatings deposited in a hydrocarbon gas environment are characterized by a lower degree of structural ordering and a lower size of Csp$^2$
clusters as compared to coatings
formed in the absence of hydrocarbon gas. In this case, a significant decrease in roughness and a decrease in microhardness are
recorded. It is shown that when C$_3$H$_8$ is introduced into the chamber up to pressures not exceeding $6.7\times10^{-2}$ Pa, there is a sharp
decrease in the coefficient of friction (to values of $0,15$) and wear of the counterbody ($0,023\times10^{-13}$ [m$^3$
(N$\times$m)]). With a further increase in the pressure of the reactive gas, an increase in the coefficient of friction and wear of the counterbody are observed.
Keywords:
carbon coatings, titanium, reactive sputtering, nanohardness, wear resistance, coefficient of friction.
