METHOD FOR ELECTROLYTIC-PLASMA POLISHING OF PART IN RAREFIED ATMOSPHERE Russian patent published in 2024 - IPC C25F3/16 

FIELD: various technological processes.

SUBSTANCE: invention relates to electrolytic-plasma treatment of metal parts and can be used, for example, for polishing blades of turbomachines from titanium alloys. Method includes immersion of part in electrolyte, formation of a vapor-gas shell around the processed surface of the part and ignition of a discharge between the processed part and the electrolyte by supplying an electric potential to the part, wherein polishing is carried out in a rarefied atmosphere at a pressure selected from range from 0.9 to 4 kPa, at an electrolyte temperature selected from range from 7 to 30 °C, and supply of positive potential to the processed part, selected from range from 10 to 80 V.

EFFECT: providing polishing of surface of part of large size, such as monowheel with blades, with simultaneous processing of the entire or most part of the polished surface of the part.
