Способ электролитно-плазменного удаления полимерных покрытий с поверхности детали из легированных сталей, включающий погружение детали в электролит, формирование вокруг обрабатываемой поверхности детали парогазовой оболочки и зажигание разряда между обрабатываемой деталью и электролитом путем подачи на обрабатываемую деталь электрического потенциала, отличающийся тем, что к обрабатываемой детали прикладывают электрический потенциал от 270 В до 300 В, а в качестве электролита используют водный раствор соли сульфата аммония концентрацией от 4 до 8 г/л, причем удаление покрытия ведут при температуре от 70°C до 90°C до полного снятия покрытия.2. Способ по п.1, отличающийся тем, что удаление покрытия с детали ведут при величине тока от 0,2 А/дмдо 0,8 А/дм.3. Способ по п.1, отличающийся тем, что удаление покрытия с детали ведут с площади от 1 смдо 4000 см.4. Способ по п.1, отличающийся тем, что в качестве детали используют пластинчатый торсион несущего винта вертолета.5. Способ по п.2, отличающийся тем, что в качестве детали используют пластинчатый торсион несущего винта вертолета.6. Способ по п.3, отличающийся тем, что в качестве детали используют пластинчатый торсион несущего винта вертолета.7. Способ по любому из пп.1-6, отличающийся тем, что в состав электролита дополнительно вводят поверхностно-активные вещества в концентрации от 0,4 до 0,8 мас.%.1. The method of electrolyte-plasma removal of polymer coatings from the surface of a part made of alloy steels, comprising immersing the part in an electrolyte, forming a vapor-gas shell around the workpiece surface and igniting a discharge between the workpiece and the electrolyte by applying an electric potential to the workpiece, characterized in that the electric component from 270 V to 300 V is applied to the workpiece, and an aqueous solution of ammonium sulfate salt is used as the electrolyte. from 4 to 8 g / l, and the removal of the coating is carried out at a temperature of from 70 ° C to 90 ° C until complete removal of the coating. 2. The method according to claim 1, characterized in that the coating is removed from the part at a current of 0.2 A / dmdo to 0.8 A / dm. 3. The method according to claim 1, characterized in that the coating is removed from the part from an area of 1 cm to 4000 cm. The method according to claim 1, characterized in that the plate torsion of the rotor of the helicopter is used as a part. The method according to claim 2, characterized in that the plate torsion of the rotor of the helicopter is used as a part. The method according to claim 3, characterized in that the blade torsion of the rotor of the helicopter is used as a part. The method according to any one of claims 1 to 6, characterized in that surfactants are additionally introduced into the electrolyte composition in a concentration of from 0.4 to 0.8 wt.%.
