description: The purpose of this work is to test the possibility of forming coatings with the structure of high-entropy alloys by microplasma spraying from composite powders of Al, Ni, Co, Fe, Cr metals and to study their set of properties. Tasks that were solved in the course of the study: 1. Homogenize powders, investigate their morphology, determine particle size, specific surface area and conduct thermogravimetric analysis 2. Carry out mechanosynthesis of the resulting homogenized mixture of metal powders under different modes (duration) of the process. 3. The resulting powder mixtures are examined for morphology, thermogravimetric analysis, and the particle size distribution is determined. 4. Carry out microplasma spraying of powders on steel samples. 5. Investigate the microhardness and porosity of the obtained coatings. Carry out X-ray diffraction analysis. 6. Examine samples for corrosion resistance. In this work, the existing methods for obtaining coatings with the structure of high-entropy alloys are studied, on the basis of which a promising method for obtaining coatings with the structure high-entropy alloys by microplasma spraying from composite powders of metals Al, Ni, Co, Fe, Cr. As a result, their characteristics were studied: morphology, particle size distribution, hardness, porosity, resistance of the mixture of powders to gas corrosion, oxidation resistance. This technique will be used in future studies aimed at optimizing the process of obtaining coatings with high-entropy alloys and desired characteristics. This will make it possible to achieve a level of technology that can be implemented at enterprises in the real sector of the Russian economy.
