Russian Scientists Combine Key Beneficial Effects in One Coating
As a result, a dense heat-resistant top layer is formed, which prevents the diffusion of oxygen from aggressive media.“Studying the structure of each layer using transmission electron microscopy, we found two protective effects: increased load-bearing capacity due to the first VESA layer and sealing of defects during deposition of the next two layers. As a result, we have obtained a three-layer coating that is one and a half times more resistant compared to its basic counterparts to both corrosion and high-temperature oxidation, both in liquid and gaseous media. This is without exaggeration an important result,” Kiryukhantsev-Korneev noted.Scientists estimate that such coatings will increase the service life and performance of critical parts of engine units, oil transfer pumps, and other components that are subject to simultaneous wear and corrosion.The Scientific-Educational Center of Self-Propagating High-Temperature Synthesis (SHS Center), headed by Professor Evgeny Levashov, brings together scientists from NUST MISIS and the Merzhanov Institute of Structural Macrokinetics and Materials Science, Russian Academy of Sciences (ISMAN). In the near future, the scientific team plans to expand the application of the combined technology to modify heat-resistant titanium and nickel alloys used in aircraft construction.
