Beschreibung
Zusammenfassung:	A method for manufacturing a chromium metal-chromium oxide coated substrate by electrolytically depositing the chromium metal-chromium oxide coating on an electrically conductive substrate from an electrolyte solution that includes a trivalent chromium compound and a chelating agent, wherein the electrolyte solution is free of chloride ions and of a boric acid buffering agent, the electrically conductive substrate acts as a cathode and an anode including a catalytic coating of iridium oxide or a mixed metal oxide is chosen for reducing or eliminating the oxidation of Cr(III)-ions to Cr(VI)-ions.
