Head Zakharova Iryna V., Доктор технічних наук Registration Date 27-06-2025 Organization State Higher Educational Institution "Azov State Technical University" popup.description1 Improvement of welding technologies for restoration and repair of parts and structures in the defense-industrial complex using electric arc surfacing, spraying and welding. popup.description2  Research Object – Welding technologies for the restoration and repair of parts in the defense-industrial complex. Purpose of the Work – To increase the wear resistance and corrosion resistance of the surfaces of restored machine parts. Research Method – Scientific and technological aspects of surfacing and spraying processes. A high-speed surfacing process using low linear energy has been developed, which ensures reduced heat input, microdistortions of the crystal lattice, microstresses, dislocation density, welding stresses, and improves crack resistance. As a result of tests of the surfaced metal samples under cold plastic deformation, the hardness of the deposited metal significantly increases, indicating self-strengthening due to dynamic martensitic transformation in the surface layer of the metal.
