Since 1969 the Swedish company Sandvik Coromant introduced the idea of surface coat cutting tools, these tools made of high speed steel HSS were initially coated tungsten carbide by chemical vapor deposition technique, all with the purpose of producing hard coatings. Since the eighties have been synthesized titanium carbide and other compounds with the physical vapor deposition technique. In this work, we establish the optimal parameters for the production of titanium nitride TiN by the technique of DC Magnetron Sputtering, initially work with leaves scalpels for this purpose, then deposited on two types of steel, steel HSS S700 Böhler widely used in manufacturing of cutting tools and steel SAE 5210. Initially work with monolayer coatings of titanium, then coated multilayers TiN/SiNx with two types of modulation ratio finding differences in hardness. Finally, we worked with composites nanostructured titanium, silicon and nitrogen; thus we obtained superhard hardness, attributing this to the size of the grains. The morphological characterization was made by SEM for TiN monolayer and multilayers in the laboratories of the Uppsala University. The chemical composition was made by EDS for SAE 5210 steel substrate and the monolayer of TiN and quantification of species by the ZAF matrix, for the multilayers and GDOES Auger spectroscopy was used. XRD for crystalline characterization was used for the multilayers and composites, calculating the lattice parameter and the grain size, except for the monolayer. Finally, as an example of application, we have covered parts for the canning y, thus the use full life cycle of the parts will be increased.
