Abstract

The paper presents the mechanism of formation of the structure and properties of coatings based on copper, aluminum, nickel, zinc, inflicted by gas dynamic spraying. Presented are the results of adhesion, cohesion, resistance to corrosion, as well as the study of the coefficient of friction coatings. Showed are the examples of using of the method for restoring of worn surfaces of machine parts and for corrosion protection engineering products.
