Abstract

The invention relates to the field of mechanical engineering and can be used in aeronautical and power turbine engineering in repairing blades or other parts of turbines, in particular in removing heat-resistant coatings from a surface of hard alloys.The process for removing heat-resistant coatings from a surface of hard alloys comprises processing of workpiece in electrolytic-plasma mode using pulsed current with a supply frequency of 50 Hz. Processing of the workpiece is carried out by bipolar pulses with a duration of 10…50 µs for the anode component and 40…200 µs for the cathode component.
