摘要
A method and apparatus for providing a surface coating of a metal or metal alloy on the wall of an elongate cavity in a workpiece by means of electrolytic plating, the workpiece being used as cathode. An electrolyte containing ions of the metal intended for the coating is brought into movement inside the cavity with the aid of a conveyor, which consists of a resilient and electrically insulating material such as perforated, net-like or fibrous strip, and which is wound helically around the anode. The strip is fringed or slit on the edge facing towards the cavity wall to form outstanding resilient fingers which are in contact with the cavity wall.
