ABSTRACT:
A movable apparatus for local electrolytic polishing of metal surfaces is disclosed, the apparatus having an arm, a supported soft surface which is attached to the arm and intended to be brought against the metal surface to be polished, and members for conducting cathodic current to this soft surface and for conducting anodic current to the metal surface to be polished. In the apparatus the supported soft surface is of an absorbent material, which is connected to the electrolyte container in order to cause electrolyte to be absorbed into the absorbent material, as electrolyte is transferred to the polished surface when the apparatus is moved. The electrolyte container may be a trough attached to the arm, the bottom of the trough supporting the absorbent material attached to its lower surface and extending to inside the trough, and the absorbent material may be some acid-resistant wadding.
