Abstract

The nanostructural and tribological characteristics of carbon nanocomposite coatings (CNCs), deposited by accelerated C₆₀ ions at high temperatures, were studied. The CNCs were successfully fabricated on Ti-alloy using a flux that contained C₆₀ ions with 5 and 10 keV energies. Unlike the previous studies, ion mass-separator was not implemented to the deposition process. This enabled deposition of sp²-rich CNCs with a lower coefficient of friction (COF) at a higher deposition rate. Laser confocal microscopy, atomic force microscopy transmission electron microscopy, Raman spectroscopy, X-ray photoelectron spectroscopy, and X-ray Auger Electron Spectroscopy were used to investigate the structure of the coatings and friction test results. A carbon nanocomposite film consisting of graphite nanocrystals enclosed in an amorphous diamond-like matrix was formed at a deposition temperature of 300–400 °C. Upon deposition of the CNC, a COF of ~0.06 was achieved, which was almost one order of magnitude lower than that of bare Ti-alloy substrate. The surface wear was reduced by 360 times. The wear mechanism was changed from abrasive wear (on bare Ti-alloy) to a burnishing smoothening of the surface roughness (on CNCs). The transfer of graphite nanocrystals from the coating to the counter surface was identified and observed to act as a solid lubricant.
