“…Among these coating materials, TiN coatings are widely used because of their superior bonding to the substrate and excellent resistance to wear, improved friction, appearance of a component, erosion and corrosion (Deng and Braun, 1994; Veprek and Reiprich, 1995; Karagoz and Fischmeister, 1996; Kelly and Arnell, 2000; Baker et al , 2002; Musil et al , 2002). Idanowski et al (1986) presented the basic physical and mechanical features of TiN layers along with the advantages and applications of TiN layers.…”

PurposeThe purpose of this paper is to examine the effect of substrate temperature on friction coefficient and surface roughness of titanium nitride (TiN) coatings deposited on high‐speed steel (HSS) using commercially available cathodic arc evaporation physical vapour deposition system.Design/methodology/approachThe goal of this work is to determine the usefulness of TiN coatings in order to improve the friction coefficient and surface roughness of HSS verses substrate temperature, as vastly used in cutting tool industry and many others. A Pin‐on‐Disc test was carried out to study the coefficient of friction verses sliding distance. Surface roughness of deposited coatings was studied via surface roughness tester and atomic force microscope (AFM).FindingsFriction coefficient increased at higher temperature as compared to the coating deposited at lower substrate temperature. Surface roughness measured via both instruments showed similar trend in recorded data and, i.e. increased by increasing substrate temperature. AFM study showed that bearing ratio (per cent) decreased, whereas, fractal dimension increased with an increase in substrate temperature.Research limitations/implicationsIt is implied that choosing a substrate temperature above 450°C in the existing coating system could damage some machine parts.Practical implicationsThis scenario develops an approach to optimize the coating properties verses substrate temperature for specific application, such as cutting tools for automobiles and aircrafts.Originality/valueThe coating deposited at lower temperature showed better friction coefficient and surface roughness than the coating deposited at higher temperature and vice versa.
