Development of energy efficient technologies innovatsinnyh strengthening and recovery of machine parts and tools

The scientific and technical task that the project is aimed at solving, the expected result: Improving the performance characteristics of machine parts and tools by modifying the structure and properties of surface layers - creating highly dispersed (nano) structures with increased wear resistance, surface hardening due to the creation of surface metal coatings with superhard fillers (highly dispersed carbides, nitrides, diamond). Expected result: improved performance of metal products, including a significant increase in their service life. Research and creation of innovative technologies for hardening machine parts and tools, in order to obtain highly dispersed structures (up to nano) and surface strengthening coatings. The scientific novelty of the solutions proposed in the draft: The novelty of the research is the use of pulsed heat treatment, including thermocyclic treatment of metal products, including alternating cycles of high-speed heating and cooling, and heating is carried out to significantly higher temperatures than with furnace heating. In addition, the modes of the subsequent heating cycle are performed with a decrease in the maximum temperature and exposure time. As a result of R&D, new information will be obtained on the mechanisms of formation of highly hard (more than 60 HRC) wear-resistant submicron (nanometric) structures and properties of surface layers (0.1-5 mm thick) of metal products, necessary for the creation of new technologies.
