Tribological properties of TiN and CrN coatings deposited by cathodic arc method at three different bias potentials -50, -150 and - 300V on Ti-6Al-4V alloy in pair with alumina have been investigated. X-ray diffraction analysis showed that single-phase textured cubic nitrides of TiN and CrN were formed in these coatings. It is shown that the friction coefficient of the coatings is practically equal to that established for the Ti6Al4V alloy, but the wear rate is more than an order of magnitude lower than for the titanium alloy substrate. Coatings deposited at a potential of -50 V show optimal tribological properties at temperatures 20 and 500°C. Friction coefficients for TiN coatings are 0.4-0.8 at 20°C and 0,75 at 500°C; for CrN coatings they are 0.5 at 20°C and 0,7 at 500°C. Wear rates for TiN coatings are 0.86·10-5 MM³/HM at 20°C and 3.56·10-5 MM³/HM at 500°C; for CrN coatings they are 1.43·10-5 MM³/HM at 20°C and 7.13·10-5 MM³/HM at 500°C. [ABSTRACT FROM AUTHOR] |
