ELECTROLYTIC-PLASMA POLISHING METHOD OF PART Russian patent published in 2020 - IPC C25F3/16 B23H9/10 

FIELD: metallurgy.

SUBSTANCE: invention relates to electrolytic-plasma machining of metal parts and can be used for polishing blades of turbomachines from nickel and titanium alloys. Method involves immersing a part in an electrolyte, forming a vapour-gas shell around the treated surface of the part and igniting the discharge between the treated part and electrolyte by feeding electric potential to the part and forming a plasma in the vapour-gas shell. During the electrolytic-plasma polishing around the processed part, a constant magnetic field of uniform intensity is created in range of 100–300 kA/m on the entire processed surface, at that, the part is treated in the mode of crossing magnetic and electric fields, at that electric potential is supplied to part from 280 to 600 V.

EFFECT: higher efficiency of treatment due to concentration of charged particles in treated surface area.
