description: Topic of the final qualification work: Â«Conducting comparative tribotechnical tests of wear-resistant steels on a serial friction machine after modernizationÂ». This work is devoted to the selection of the most suitable material for excavator bucket teeth as a result of comparative studies of mechanical, metallographic and tribotechnical properties of three wear-resistant steels with structural steel. Tasks that were solved during the work: 1. Study information about wear-resistant steels, tribotechnical tests, abrasive wear and surface roughness. 2. Modernize the SMC-2 serial friction machine. 3. Conduct tribotechnical tests of steels on the upgraded friction machine with the accompanying removal of tribotechnical characteristics. 4. To investigate the mechanism of wear of the tested samples. 5. Examine the surface roughness of the samples before and after wear tests. 6. To conduct a study of the microstructure of steels. 7. Identify the correlation dependences of the parameters and choose a steel grade that has optimal mechanical, tribotechnical properties and the best structural-phase state.Â As part of the work, all the tasks were completed and, based on the conducted research, the most suitable steel grade was selected.
