Popis: Mechanical and tribological properties of thin films draw special attention and differ from those of bulk materials due to the effects of interfaces, microstructure and thick underlying substrates. In this study hard wear resistant nitride coatings (TiN, ZrN, TiAlN, TiCN and CrN) were coated on high speed steel substrates using cathodic arc deposition method. Mechanical properties of the films were evaluated using nanoindentation technique. Continuous stiffness method was employed to evaluate the depth sensing hardness and modulus values. Studies of tribological properties were performed using ball-on-disk friction and wear test. We have also investigated the wear track using optical microscopy. Variation of coefficient of friction with time has been analyzed and coating endpoint was estimated. Nanoindentation evaluation of mechanical properties along with the measurement of tribological properties is very useful in order to use them as wear resistant hard coatings.
