Mechanical behavior and corrosion of steeltools nitrided and coated PAPVD
In recent years, surface engineering has been employed for the optimization of coated systems, as well as other surface treatments, by means of plasma-assisted technologies. Hard coatings obtained both by PAPVD and PACVD can improve significantly the surface properties of the substrate in terms of its mechanical properties and corrosion resistance. Coatings are an integral part of the expansion of new surface engineering technologies. Therefore, the surface engineering field seeks the development of new techniques and materials in order to optimize such coated systems. The ultimate aim is to provide them with the required microstructural features to ensure suitable surface properties and to increase the life of industrial parts and components. This paper presents the main results of the characterization of the mechanical properties and corrosion resistance of a TiN and TiAlN coatings deposited onto D2 and H13 tool steels by PAPVD. The steel substrates were employed both in their original condition, as well as after nitriding.
