Tribological and microstructural analysis of multilayer ceramic films on D2 and 440 steels

The objective of this work is to carry out the microstructural and tribological characterization of D2 and 440 steel substrates, coated with films whose architecture is TiAlN and AlTiN respectively, the samples that were characterized are obtained from the collaboration with the company SADOSA S.A. de C.V., who work coatings at an industrial level. The methodology that was used is divided into two aspects, within the microstructural characterization section, the samples were subjected to various microscopic analysis techniques (MEB) to observe the surface and by means of energy disperse spectroscopy (EDS) to corroborate the presence of the elements. in the film, through the use of calotest the thickness of the film was obtained and through optical profilometry to determine the surface topography. In the tribological characterization section, wear studies were carried out such as bolt on disc, obtaining information on the wear coefficient and by using the VDI 3198 standard, information on its adhesion was obtained.
