Abstract
The paper studies the possibility of applying the coatings produced by cold spraying, for the protection and repair of aircraft structural elements of aluminum alloy against corrosion damage during service of aircrafts. Mechanical tests were carried out on samples, made of aircraft alloy 1163RDTV, and repaired by cold spraying after corrosion damage. It is shown that the coating production via cold spraying on corrosively damaged areas can restore the strength characteristics of the sample in the elastic region of deformation diagrams. The preliminary results of the influence of cyclic loading on repaired by cold spraying samples were also obtained. It is shown that the characteristics of durability increased by factor 1.67 in comparisons with the sample that was not repaired after corrosion damage.
