| 摘要 |
The invention relates to a method for producing a corrosion protective coating for a substrate made of light metal or of a light metal alloy. According to the invention, a non-electrically conductive first layer (10) is first deposited on the substrate (5), whereby the non-electrically conductive first layer (10) is produced by anodic oxidation of the substrate (5). Later, the non-electrically conductive first layer produced by anodic oxidation is subjected to a redensification. Afterwards, a metallic layer (20) is deposited on the non-electrically conductive first layer (10) without using current. Later, a third layer (30) is deposited on the metallic second layer (20). By using this method, wheel rims and wheel trim, for example, for motor vehicles can be chromed.
