A Review on Recent Progress in PVD-TiN Coatings

Hard nitride coatings has an important role for enhancing the wear resistance of metallic materials, thus increasing the life time of the products in industries. In this paper reviews the different methods of coating techniques, methods of PVD, mechanical properties of TiN coatings and wear resistance of titanium nitride-based coatings by physical vapor deposition (PVD) techniques. Thus the various approaches for enhancing the corrosion and wear resistance are categorized and summarized. The advantages, disadvantages and applications of Nitride based coatings are discussed.
