ABSTRACTMechanical 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.

Arc Deposition

To mitigate costly surface damage, compressor blades are coated with materials that resist corrosion and resist wear from particle impact. Large Area Filtered Arc Deposition (LAFAD) technology has demonstrated the capability of depositing relatively thick cermet coatings with microlaminated architectures forming a stack of metallic/ceramic bi-layers. These coatings have nearly defect-free morphology and an extremely smooth surface with high surface energy, which improves the aerodynamics of airfoils. Yet, the deposition process can be carried out at a speed that produces coatings sufficiently thick to provide long life protection from particle damage at a cost-effective production rate. The basic mechanical properties and erosion resistance of LAFAD microlaminated cermet coatings deposited on Ti6Al4V and 17-4PH steel substrates have been investigated as a function of coating composition and architecture.
