| 摘要 |
The invention relates to a method for coating moulded bodies, containing copper or copper alloys, or moulded bodies having a coating, containing copper or copper alloys, comprising, the following steps in succession: a) providing a moulded body containing copper or at least one copper alloy, or a moulded body having at least one coating containing copper or at least one copper alloy, h) treating the moulded body with at least one aqueous system, in particular at least one aqueous solution, of at least one fluorine complex of at least one element selected from the group consisting of B, Si, Ti, Zr and Hf and/or with at least one acid aqueous system, in particular an acid aqueous solution, containing at least one fluoric acid of an element selected from the group consisting of B, Si, Ti, Zr and Hf, m) EPD treatment of the moulded body with at least one cathodically precipitable electrodeposition paint (EPD coating step), and p) annealing the moulded body. The invention further comprises coated moulded bodies. |
