Abstract

A device for electrolytically coating an object is disclosed. In one aspect, the device includes an electrolyte container containing an electrolyte and a first DC power source. The device also includes at least one soluble anode which is at least partly immersed into the electrolyte and electrically conductive connected to a positive pole of the first DC power source. The device also includes at least one cathode terminal which is electrically conductive connected to a negative pole of the first DC power source and to which the object is electrically conductive connected, the object being immersed into the electrolyte. The device further includes a second DC power source configured to operate independently of the first DC power source and at least one insoluble anode, which is at least partly immersed into the electrolyte and electrically conductive connected to a positive pole of the second DC power source.
