V originále

Nanocrystalline titanium carbide embedded in an amorphous (hydrogenated) carbon matrix is a versatile nanocomposite material which, being deposited as thin film, combines the properties of hard titanium carbide nanocrystallites and relatively soft hydrogenized carbon matrix. Hybrid PVD-PECVD process of titanium sputtering in a mixture of argon and acetylene at optimized deposition conditions enables us to deposit superhard nc-TiC/a-C:H coating with hardness and Young’s modulus over 40 GPa and 400 GPa, respectively with good adhesion on Ti coated HSS and WC and thickness higher than 5 µm. Further mprovement of the mechanical properties of these coatings was tested by adding third, non carbide formig, element by placing small number of nickel evaporation pellets on the racetrack of the magnetron target. Set of samples with different Ti/C ratio was prepared for different Ni doses. Influence of the Ni content on the properties of nc-TiC/a-C:H system was evaluated. XRD was used to determine crystalite size and latice parameter; depth sensing indenter to get hardness and Young modulus. XPS and EDX provided chemical composition of prepared samples. This research has been supported by the CZ.1.05/2.1.00/03.0086 and GACR P205/12/0407 projects.
