ТАСС: Russian Development to Increase Wear Resistance of Titanium Alloys for Aviation

26.01.2026

The indicator will grow through high-energy electromechanical treatment of the material.
Scientists at Volgograd State Technical University (VSTU) have developed a technology that increases the wear resistance of titanium alloys tenfold through high-energy electromechanical treatment (EMT) of the material. Such solutions are in demand in the aviation and aerospace industries, as well as in mechanical engineering and the defense-industrial complex, the head of the "Strength of Materials" department at VSTU, Igor Zakharov, told TASS.
"Improving the durability and reliability of parts made from titanium alloys is important in the manufacture of engine components, landing gear, structural load-bearing elements, and fasteners, which are in demand in the aviation, aerospace industries, and the defense-industrial complex. Our development based on EMT involves simultaneous exposure of the material to high temperatures and contact pressures. In this way, we have increased wear resistance tenfold. If previously a part's critical wear level was reached after 150,000 cycles, after strengthening the part withstands over 1,500,000 cycles," said Zakharov.
He noted that the development is also in demand in general mechanical engineering and medicine.
"In mechanical engineering, such technology is applicable for optimizing the surface hardening of parts and components of marine vessels, petrochemical and food equipment, medical prostheses, and more, allowing to increase equipment lifespan and reduce repair and replacement costs," Zakharov noted.
The scientist added that the development is being carried out within the framework of the project "Prediction and Control of Properties of Titanium Alloys Based on Cyclic Strength and Durability Using High-Energy Impacts," which is supported by the Russian Science Foundation.
