Scientists from NUST MISIS have proposed a new approach to modify alloy surfaces for medical purposes

Researchers from NUST MISIS have proposed a new two-stage method for modifying alloys, which are promising for manufacturing orthopedic implants that require special mechanical and functional properties. By using atomic layer deposition on the surface of a superelastic Ti-Zr-Nb (titanium-zirconium-niobium) alloy, they were able to obtain an oxide film (TiO₂) that allows for controlling the chemical state of the material. Subsequently, silver nanoparticles were applied to the alloy, significantly increasing the antibacterial activity of the material.

Steel that saves lives

Scientists from NUST MISIS, in collaboration with Severstal, have developed a new Russian fire-resistant grade of steel, C390P, for industrial and civil facilities such as trade and business centers, warehouses, transport hubs, and multi-story garages. Structural metal constructions made from this steel can withstand a fire temperature of 600°C for about 30 minutes without losing their load-bearing capacity. This helps slow down the destruction of buildings during fires, providing additional time for people to evacuate. Fire-resistant products made from C390P steel are already being produced at the Severstal Steel Solutions plant. The project was implemented with the support of the Russian government as part of the program to develop high-tech domestic production. The development received a gold medal at the Metal-Expo 2023 exhibition.
