The peculiarities of the industrial technology of deposition of plasma heat-protective coatings on the blades of gas turbine units using CoCrAlYSi powders obtained from the corresponding alloys of electron-beam melting are described. The necessity of controlled surface preparation of the blades before coating is shown. The time between surface cleaning and coating is regulated. The optimal technological parameters of the coating are indicated and their structural and chemical composition is investigated. Ref. 5, Tabl. 1, Fig. 3.
