Modeling of Phase Transformation in the Production of Self-Propagating High-Temperature Synthesis of Wear-Resistant Coatings




Abstract: The paper presents the results of the physico-chemical modeling of the production of doped chromium-plated coatings using the technology of selfspreading high-temperature synthesis. The influence of the composition of the reaction charge on the thermal characteristics of the process and the coating thickness was studied. Toughness tests were carried out on a CMT-1 friction machine, the test time was 5 hours, at a rotation speed of 500 rpm (roller), the load on the test sample was P = 500 N. Siliconized layers doped with chromium have a wear resistance of 1.8-2.1 times that of uncoated samples. The conducted studies show that the SHS technology for obtaining doped chromium-plated coatings makes it possible to obtain wear-resistant protective coatings with limited time for their formation.
