Анотация: The FeCoCrNiTaTiMo alloy and coatings based on it have been synthesized by mechanical alloying. - The optical microstructure of high-entropy coatings exhibits irregularity, which is clearly visible on the maps of energy-dispersive spectroscopy. XPS spectra indicate the formation of high-entropy coatings. Analysis of the elemental composition shows the complexity of the high-entropy alloy FeCoCrNiTaTiMo. The structure consists of solid solutions with a chaotic arrangement of atoms of elements. The microhardness of our coating (345 HV) is not inferior to stainless steels, and the wear resistance of the coating is 3•10-4 g/min. High-entropy FeCoCrNiTaTiMo coatings turn out to be antifrictional, which obviously leads to energy savings. The thickness of the surface layer d(I) is determined by one fundamental parameter - the molar (atomic) volume of the element and is equal to 12.3 nm. it is shown that the formation of a cellular nanostructure in a coating can ocMor according to several models.
