PURPOSE[br][/br]to restore (harden) worn cylindrical surfaces (brake drums, neck and axle journal, working in tandem with rolling bearings (sliding))[br][/br]to restore (harden) flat parts (guides, friction disks)[br][/br]corrosion protection of parts,structures’ components and facilities [br][/br]manufacturing of bimetallic "steel-bronze" pistons instead bronze ones
Technology Type

Technology Benefits
Competitive advantages[br][/br]• minimum porosity of coatings (steel ≤ 4 %) with a bond strength of more than 60 MPa;[br][/br]• performance of 16–18 kg/h, which is twice as high as that of high-speed methods of[br][/br]powder spraying;[br][/br]• the cost of application of 1 kg of coating is 3–10 times lower than the known highspeed[br][/br]coating application methods use;[br][/br]• galvanic chrome plating can be replaced.

Technology Differentiation and Uniqueness
The technology of hypersonic metallization, different from traditional electrometallization[br][/br]using a continuous source of energy to heat the gas, spraying the arc melted wire. Gas, heated to a temperature of about 2000 °C, flowing through the Laval nozzle, has a speed of 900–1300 m/s, which allows dispersing the particles of the atomized material to velocities of more than 400 m/s.

Context in which technology was identified
The equipment is produced and a number of technological processes for applying wearresistant,[br][/br]corrosion-resistant, antifriction coatings on machine parts and structural elements are developed. The recommendations on the organization of specialized sites are developed.
