Tribological properties of nanostructured DLC coatings deposited by C60 ion beam

► Nano-composite of graphite nanocrystals in diamond-like matrix was fabricated. ► Nanostructure of coatings deposited by ion beam varies with substrate temperature. ► Tribological properties of the coatings depend on graphite/DLC ratio. ► Coatings deposited at 200-300 °C demonstrate excellent tribological properties.
