In a process for the galvanic copper coating of a workpiece (50), in particular a pressure cylinder (50), copper sulphate (74, 79) is fed to a sulfuric acid copper bath (30, 32, 34) for supplying copper. An electrolytic bath (30, 32, 34) contains in solution copper and sulfuric acid, and copper carbonate is added to the electrolytic bath. Use of copper carbonate (74, 79) for supplying copper in a sulfuric acid copper bath for a galvanic copper coating. A plating apparatus (10) for carrying out such a method is shown. |
