FIELD: chemistry.
SUBSTANCE: invention relates to a layered system with the MCrX layer and a chrome-enriched layer. The layered system (1) contains a substrate (4) and a multi-layered coating, and the multi-layered coating contains one MCrX (7, 7') layer as the lowest layer (7, 7') on the substrate (4), in which X is at least yttrium (Y) and/or silicon (Si), and/or aluminium (Al), and/or boron (B), in which M is nickel (Ni) and/or cobalt (Co), the chrome-enriched layer (10) on or in at least one MCrX layer (7, 16) and the first outer MCrX" layer (13), which is located on the chrome-enriched layer (10), where X" is, at least, Y, Si and/or B, with the said lower MCrX (7) layer being present on the substrate (4) and under the chrome-enriched layer (10). In the process of preparing the layered system (1), at least, one MCrX (7, 7', 16) layer is applied, in particular, by a method of a high-velocity oxygen fuel coating.
EFFECT: layered system resistant to oxidation and high temperature corrosion is provided.
