 Physical vapor deposition technique is used to deposit hard and wear resistant thin film of coating material into the substrate surface without changing the substrate properties; commonly referred as thin films. Hard thin film coatings are employed to enhance the surface characteristics of the substrates such as hardness, surface roughness, wear resistance and corrosion resistance without changing the bulk properties of the substrates. Demands for transition metal nitrides such as TiCN, TiCrN, TiAlN, CrAlN synthesized by physical vapor deposition (PVD) as hard film coatings are increasing rapidly due to their superior mechanical, tribological, and corrosion characteristics, thus increasing the components life and productivity of the production. These metal nitride coatings are used to improve friction, wear and life of cutting tools, mould and dies, machine elements, automotive components. Type of coating applied on the substrate depends on the applications of that component.
