Functional coatings application for strengthening and restoration of aviation products

The article deals with the analysis of modern technologies of surface hardening and restoration of the working parts of aviation products. The technologically sophisticated methods of obtaining multifunctional composite coatings with an application of effective sources of energy are described. These methods permit structures with predetermined physical and mechanical properties to be formed on working surfaces. The results of testing alloys and coatings under conditions of abrasive and erosive wear are tested. Practical recommendations on application of the aircraft parts surface strengthening and restoration techniques, taking into account conditions of operation, are brought forward.
