FIELD: metallurgy. ^ SUBSTANCE: body made from steel, hard metals, cermets or ceramics and covered with hard material with single-layered or multi-layered systems of layers contains at least one solid layer Ti1-xAIxN, which has been obtained by chemical deposition from gaseous phase. Solid layer represents either single-phase layer of cubic NaCl-structure and stoichiometric coefficient x > 0.75 to x = 0.93, and constant grid afcc between 0.412 nm and 0.405 nm, or multi-phase layer the basic phase of which consists of Ti1-xAIxN with cubic NaCl-structure, with stoichiometric coefficient x > 0.75 to x = 0.93, and constant grid afcc between 0.412 nm and 0.405 nm. In addition to the basic phase the layer also contains the other phases from Ti1-xAIxN with wurtzite structure, and/or from TiNx with NaCI-structure; at that, chlorine content of solid layer of Ti1-xAIxN lies within the range of 0.05 to 0.9 atomic %. Bodies made from steel, hard metals, cermets or ceramics are coated with single-level or multi-level system of layers, which contains at least one solid layer of Ti1-xAIxN. To the bodies there applied is coating in rector at temperatures of 700C to 900C by means of chemical deposition, as precursors there used are titanium halides, aluminium halides, and reactive nitrogen-containing compounds which are mixed at increased temperatures. ^ EFFECT: obtaining bodies with coatings, which have improved wear resistance characteristics and resistance to oxidation. ^ 10 cl, 2 dwg, 2 ex |
