Annotation The coatings on steel U10A received based on Ti, V and Cr, which have been optimized by simplex lattices Scheff and studied by soft X-ray spectroscopy. It is shown that the maximum amount of carbon in such coatings ТiС, (Тi, V, Сr)С is respectively in their outside and central areas. Reducing the amount of carbon in the coating (Ti, V, Cr) C, compared with ТiС coating, is reflected in the significantly narrowed TiL- bands in the energy spd-hybrid bonds. The interaction of atoms of titanium and iron in the central and inner zones carbide layer shown in TiLα-bands. In the central areas and inner surfaces formed links Ti-Fe-C, which manifests itself in prifermiyevskomu influx TiLα- and SKα-bands. It is established that changing microhardness, thickness mikrofragility coverings in well with the level of cooperation Me-C in various areas carbide phases.
