FIELD: machine building.
SUBSTANCE: present invention can be used in aircraft and power turbine engineering to repair blades and other parts of turbines. Method involves treatment in electrolyte containing an inorganic ammonium salt and an additive of a water-soluble substance, wherein the treatment is performed in the electrolyte-plasma cathode mode where power supply is provided by direct current impulse bursts with the frequency of 30-40 kHz and the pause between the impulses of 4-10 mcs in electrolyte containing in wt%: ammonium fluoride 2-5; trilon B 0.01-0.03 and the rest is water.
EFFECT: to increase the yield of good items during the removal of coating and to low power consumption while maintaining or increasing the rate of coating removal.
