Abstract
Phase and chemical compositions, structures and microhardness of diffusion coatings, containing titanium and aluminium, were studied on samples of steel 12Cr18Ni10Ti. Depending on the type of treatment the multilayer coatings on titanium carbide and nitrite base, intermetallics and oxides of titanium, aluminium, nickel, chromium, iron, as well as solid solutions of titanium and aluminium in austenite are formed in steel. It was found that during chemical-thermal treatment the titanium nitrite layer has a function of a barrier, delaying the aluminium and titanium diffusion into a base and the base components – into a coating.
