PROCESS OF ELECTROLYTIC DEPOSITION OF COAT ON INTERNAL SURFACE OF HOLLOW ARTICLE Russian patent published in 2000 - IPC

FIELD: electroplating, mechanical engineering. SUBSTANCE: in accordance with process of electrolytic deposition of coat on internal surface of hollow article anode is placed in space of article and is plastically deformed by clips moved length-and sidewise over surface of deposition is process of deposition of metal. At same time concentrated solution is fed into space of article and depleted solution is brought out. Article is given reciprocating motion and clips are rotated uniaxially with anode. Concentrated solution gets into space of article with the aid of system of blades which rotate simultaneously with anode and are positioned at angle α with butt of article. Angle α is chosen from condition . EFFECT: enhanced quality of coat and expanded range of articles thanks to simplification of equipment employed in process and increased reliability of circulation of solution. 4 dwg
