COMPARISON OF STRUCTURE AND MECHANICAL PROPERTIES OF nc-TiC/a-C(:H) AND nc-(Ti,Ni)C/a-C(:H) COATINGS
Original language description
Nanocomposite coatings composed of nanocrystalline grains of titanium carbide embedded in an amorphous carbon matrix, nc-TiC/a-C(:H), are widely studied due to their mechanical properties such as high hardness [1]. One of the main parameters that determines the final mechanical properties of nc-TiC/a-C(:H) coating system is the relative content of nanocrystalline and amorphous phase. Selective doping of this system by a non-carbide forming element such as nickel is a possible tool for influencing this parameter [2]. Hybrid PVD-PECVD process of titanium target sputtering in a mixture of acetylene and argon was used to deposit nc-TiC/a-C(:H) coatings [3]. Titanium-nickel (92.5 % Ti, 7.5 % Ni) target was used for preparation of nickel doped coatings. Varying acetylene flow rate was used in order to prepare coatings with different content of C in coatings. Several sets of Ni-free nc-TiC/a-C(:H) and Ni-dopped nc-TiC/a-C(:H) coatings were prepared and compared.
