Abstract(es_ES)

En los últimos años, la ingeniería de superficie ha venido optimizando los sistemas recubiertos y tratamientos superficiales mediante la aplicación de tecnologías asistidas por plasma. Tanto los recubrimientos duros obtenidos por PAPVD como PACVD pueden proveer una mejora significativa en las propiedades superficiales del substrato en términos de sus propiedades mecánicas y resistencia a la corrosión. Los recubrimientos hacen parte integral del desarrollo de nuevos materiales y se busca desarrollar técnicas y materiales que permitan optimizar los sistemas para conferirles las características microestructurales que garanticen el perfil de propiedades idóneo para mejorar la eficiencia e incrementar la vida útil de los componentes industriales y dispositivos. Por lo tanto, este trabajo presenta los resultados de la caracterización de sistemas recubiertos a base de TiN y TiAlN obtenidos mediante deposición física en fase vapor asistida por plasma (PAPVD), en cuanto a su comportamiento mecánico y frente a la corrosión, cuando se utilizan como substrato los aceros de herramienta D2 y H13, tanto en su condición original como nitrurados.

Abstract(en_US)

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.
