METHOD FOR TREATMENT OF INNER AND OUTER SURFACES OF ARTICLES MADE BY AN ADDITIVE METHOD, AND A DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2019 - IPC C25F3/16 

FIELD: technological processes.

SUBSTANCE: invention relates to plasma engineering for electrolytic-plasma treatment of articles of complex shape made using additive technologies. Electrolytic-plasma treatment of internal surfaces of articles of complex shape is carried out using an additional switchable flexible cathode, which is introduced into inner cavities of part or is supplied to outer surface of article by a given distance. Device for local treatment of inner and outer surfaces of articles made by an additive method is characterized by using a flexible movable cathode enclosed in a flexible dielectric hollow shell in the inner space of which an electrolyte is pumped. Cathode is introduced into the inner cavities of the processed article being an anode.

EFFECT: reduced degree of roughness of external and internal surfaces of parts made using additive technologies.
