METHOD FOR ELECTROLYTIC-PLASMA POLISHING OF PART IN MAGNETIC FIELD UNDER CONDITIONS OF LOW PRESSURE 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 involves immersing a part in an electrolyte, creating a magnetic field around the processed part with an intensity in range of 50-500 kA/m, formation of vapour-gas shell around processed part surface and ignition of discharge between processed part and electrolyte by means of electric potential supply to part. Polishing is carried out at reduced pressure selected from 0.9 to 4 kPa, at electrolyte temperature selected from 7 to 30 °C, and when the processed part is supplied with a positive potential selected from range from 10 to 80 V.

EFFECT: uniform polishing of large part surface at simultaneous processing of all or most part of its polished surface.
