FIELD: electroplating processes, possibly deposition of high quality predetermined size coating onto inner surface of hollow article.
SUBSTANCE: method comprises steps of arranging anode together with clamps in cavity of article; plastically deforming (by means of clamps) metal being deposited out of solution; moving clamps along length of surface to be deposited and simultaneously across said surface; supplying into cavity of article concentrated solution and draining from it depleted solution; supplying solution into cavity of article at side of article end and pumping solution along surface to be deposited with use of system of ribs on anode surface. Said ribs are arranged along helix by angle β relative to end of article. Said angle is selected according to condition β is less than β<|±π/4|.
EFFECT: highly stable quality of coating, enlarged assortment of products due to simplified equipment of high mobility, reliable circulation of solution in deposition zone.
