Abstract
A method is described for electroplating a cylindrical inside surface (4) of a work-piece (3) extending substantially over a semi-circle, with an electrolyte being conveyed from a bath (8) in a circulation through a gap (9) between the inside surface (4) and a revolving guide means (6). In order to ensure advantageous coating conditions it is proposed that the electrolyte is conveyed with the help of the guide means (6) immersed only partly in the bath (8) in the circumferential direction through the gap (9) between the guide means (6) and the work-piece (3) guided outside of the bath (8).
