The method for coating the molded bodies containing copper or copper alloy or the molded bodies with a coating containing copper or copper alloy, comprises providing molded body or molded body with the coating, iron phosphate and/or zinc phosphate of the molded body, rinsing the molded body with the aqueous system and/or drying the molded body, treating the molded body with the aqueous base solution and/or aqueous acid solution, and rinsing the molded body with aqueous system comprising valkyrie environmental water and/or drying the molded body. The method for coating the molded bodies containing copper or copper alloy or the molded bodies with a coating containing copper or copper alloy, comprises providing molded body or molded body with the coating, iron phosphate and/or zinc phosphate of the molded body, rinsing the molded body with the aqueous system and/or drying the molded body, treating the molded body with the aqueous base solution and/or aqueous acid solution, rinsing the molded body with aqueous system comprising valkyrie environmental water and/or drying the molded body, treating the molded body with an aqueous solution of a fluorine complex of element containing bismuth, silicon, titanium, zirconium and hafnium and/or aqueous solution of a fluoric acid of element containing bismuth, silicon, titanium, zirconium and hafnium, cathodically depositable electro-deposition lacquer (KTL) treating the molded body with a cathodically depositable electro-deposition lacquer, and annealing the molded body. A color coating or a transparent coating is produced in the KTL coating step. The copper alloy contains or represents brass. The pH-value of the aqueous base solution is >= 10. A cationic epoxy resin is used in the KTL-coating step. An independent claim is included for a coated molded body. |
