Abstract

Provides an overview of coating removal methods widely used in the aviation industry to prepare the surface of used parts for subsequent restoration and repair. The analysis of the main advantages and disadvantages methods of removing coatings is carried out. The results of the application of the promising method of electrolyte-plasma treatment are also presented.

For the first time in the domestic and foreign aviation industry, VIAM has developed a comprehensive technology for repairing spent turbine blades, including removing coatings by electrolytic-plasma surface treatment.
