| Abstract Scope |
The paper considers the SHS gas transportation technology for the production of protective coatings from boron alloyed with chromium on steel. Using the method of mathematical modeling, optimal compositions of SHS mixtures have been developed for applying wear-resistant coatings to parts of machines operating in conditions of shock-dynamic stress. The test results of steel samples for wear under friction on a friction machine SMT-1 indicate a significant increase in the wear resistance of the processed samples. Tests on the MT-5 friction machine (friction under sliding friction conditions) showed that Si-doped protective coatings provide the best wear resistance. When sliding friction tests of titanium coatings doped with boron, the wear resistance of coatings with a titanium coating is 1.6-1.9 times higher compared to control samples. The SHS method provides high surface quality. |
