The use of self-propagating high-temperature synthesis and argon-arc overlaying when strengthening the surface of products made of titanium alloys

A new method for the deposition of protective coatings (wear-resistant overlaying) that are 2 to 10 mm thick and more on the surface of titanium articles is suggested, developed, approved, and patented. The method, called “SHS-arc overlaying,” combines the exothermic synthesis of adding material (AM...

Description
Summary:A new method for the deposition of protective coatings (wear-resistant overlaying) that are 2 to 10 mm thick and more on the surface of titanium articles is suggested, developed, approved, and patented. The method, called “SHS-arc overlaying,” combines the exothermic synthesis of adding material (AM) and argon-arc overlaying, which proceed simultaneously with the deposition of the coating. AMs made of exothermic mixtures are developed. Using this new method, protective composite coatings for titanium articles are obtained. The physicochemical, microstructural, and exploitation properties of the overlaying are investigated. Its operational characteristics exceed the characteristics of standard samples by a factor of 1.5–2.0. This new technology can be recommended for the deposition of protective coatings on products of wide indentation made of titanium alloys.
