| description | The present invention relates to a process for the formation of colored conversion coatings on aluminum substrates using an acidic aqueous composition comprising chromium(lll), the elements Mo and/or W, a source of fluoride, and at least one oxidizing agent having a standard reduction potential in a range from +1,0 to +1,8 V (SHE). The invention further relates to an acidic aqueous composition that can be used in such a process and its use. |
