COATING SYSTEM, COATED COMPONENT AND METHOD FOR PRODUCTION THEREOF Russian patent published in 2014 - IPC C23C28/04 C23C14/06 C23C14/34 

FIELD: chemistry.

SUBSTANCE: invention relates to coated components and production thereof. A multilayer coating contains at least one type A layer, wherein the type A layer substantially consists of (Al_yCr_1-y)X, where X denotes one element from a group consisting of N, CN, BN, NO, CNO, CBN, BNO and CNBO, y describes a stoichiometric composition of a metal phase fraction, at least one type B layer, wherein the type B layer substantially consists of (Al_uCr_1-u-v-wSi_vMe_w)X, where X denotes one element from a group consisting of N, CN, BN, NO, CNO, CBN, BNO or CNBO, wherein Me denotes one element from a group consisting of W, Nb, Mo and Ta, or a mixture of two or more constituents of said group, u, v and w describe the stoichiometric composition of a metal phase fraction, wherein the ratio of the thickness of said type A layer to the thickness of said type B layer is greater than 1. The method of producing a component with said multilayer coating is characterised by depositing at least one type A layer onto said surface of the component and depositing at least one type B layer onto said component. Said at least one type A layer is deposited using n_x targets. Said at least one type B layer is deposited using n_y targets, wherein n_Xy targets used to deposit the type A layer are simultaneously used, wherein n_x, n_y and n_Xy are integers greater than or equal to 1, and at least one of said targets used to deposit the type A layer is active at both steps a) and b).

EFFECT: obtaining a multilayer coating having improved wear resistance, mechanical and thermal properties, particularly hardness at high temperatures and oxidation resistance.
