A titanium coating containing TiN or alumina ceramic additives are studied on a Ti-6Al-4V substrate after a direct laser metal deposition in different gas environments (nitrogen, argon). The manufactured graded layers are then comparatively estimated by scanning with the electron microscope equipped with the element analysis facilities. The possibilities to synthesize TiN by the method of a direct laser metal deposition in a nitrogen environment and to produce functional graded coatings with a high microhardness were shown. A significant increase in microhardness in the layers cladded out of the Ti-Al 2O 3 mixture compared to that of the titanium substrate was accompanied considerable amount of cracks.
