Caracterización microestructural de una película delgada basada en nitruro de titanio resistente a corrosión de alta temperatura

Abstract

This project will focus on characterizing titanium-based thin films that cover the valves used in an internal combustion engine converted to compressed natural gas vehicle used in a project carried out at the UPTC university. In this case, the thin films will be recreated by means of the “SPUTTERING” technique by magnetron trying to maintain the conditions proposed in the UPTC work. The coatings will be analyzed by means of X-ray diffraction (XRD) techniques to determine the crystalline structure, lattice parameter, crystalline size, microtress and crystallographic texture coefficient. In addition, X-ray fluorescence spectroscopy (XRF) will be used to observe the elemental chemical composition and optical microscopy (OM) to observe the surface condition of the film.
