The paper presents the results of the physical and chemical modeling of the production of doped chromium-plated coatings using the technology of self-spreading high-temperature synthesis on brass. A model was developed for the process of formation of doped chromium-lated in the conditions of thermal autoignition, which consists of 5 stages. Tests were conducted on the corrosion resistance of the obtained alloyed protective coatings. The conducted researches show that the SHS technology for obtaining doped chromium-plated coatings allows obtaining corrosion-resistant protective coatings with limited time of their formation.
