In response to environmental issues and the intensive degradation of parts, the civil and military aviation industries have shown increasing interest in developing more sustainable materials and technologies; therefore, this paper proposes the regeneration of structural components by cold spraying. As part of this research, Ti–Al composite powder was deposited by low-pressure cold spraying and then heat treated to obtain a Ti–Al3 intermetallic phase. The Ti–Al3 intermetallic phase is characterized by high hardness and abrasion resistance. The research has shown that at appropriately selected heat treatment parameters, this phase is formed in a certain area of the Ti–Al coating. The presence and morphology of the Ti–Al3 phase were confirmed by X-ray, scanning, and transmission electron microscopy. It has been found that the presence of this phase increases the hardness of coatings and reduces the friction coefficient.
