Abstract (en)
[origin: WO2022229175A1] The invention relates to a device for coating a component or semi-finished product with a chromium layer, the device comprising an undivided deposition cell, in which there is an anode and which is suitable for receiving a cathodically connected component, wherein: there is an electrolyte solution containing chromium(II) in the deposition cell; the device has an electrolytic cell, which is divided by a membrane disposed in the electrolytic cell into a cathode chamber, in which there is a cathode, and an anode chamber, in which there is an anode; the cathode chamber is connected to the deposition cell by means of a line and a pump disposed in the line; the pump can pump liquid from the cathode chamber into the deposition cell and/or can pump liquid from the deposition cell into the cathode chamber.
