The article examines the morphology of high-entropy coatings formed using vacuum technologies on low-carbon steel substrates. Studying the morphology of the surface layers of TiAlSi (N ,C ) coatings formed on low-carbon steel substrates using atomic force and optical microscopy methods made it possible to establish the dependence of the morphological parameters of the coatings on the energy parameters and chemical composition of the substrate. The dependence of the morphological parameters of coatings on the conditions for the formation of vacuum layers on low-carbon steel substrates is also shown.

The most common coatings for metalworking tools include titanium nitride, titanium carbide, titanium carbonitride, zirconium nitride, zirconium carbide, zirconium carbonitride, compounds based on chromium, titanium, aluminum, diamond-like coatings that are formed in vacuum using PVD, CVD, PCVD methods or a combination of the above methods. The current trend in the deposition of vacuum coatings is the production of multifunctional coatings, which can significantly increase operational characteristics compared to the starting materials. To form multifunctional coatings, the creation of “sandwich” structures is used, since each layer performs various functions – forming, antiwear, anticorrosion. Thus, the use of a composite multilayer coating containing layers of titanium nitride, titanium, diamondcontaining compounds with a thickness of one layer from 0.1 to 2 microns makes it possible to increase the wear resistance of a metalworking tool by 1.5-5 times.
