Abstract—The results of studying the restoration of aluminide coatings during the repair of gas turbine blades are presented. The main factors influencing the process of removing protective coatings and excluding the destruction of the surface layer of the blade material, namely, the electrolyte composition, the electrolyte heating temperature, and the time of etching of the blades, are given. The etching rate is shown to depend significantly on the phase composition of the coatings. The main sign of the completeness of the removal of the coatings and the preservation of the ability of the blades to take mechanical loads is found to be partial preservation of the diffusion zone of the coatings.
