Abstract: The invention relates to a method for creating an anticorrosive coating layer, wherein a surface to be treated is brought into contact with an aqueous treatment solution comprising chromium(III) ions and at least one phosphate compound, wherein the ratio of the concentration of the substance amount of chromium(III) ions to the concentration of the at least one phosphate compound (calculated in relation to orthophosphate) lies between 1:1.5 and 1:3. The method improves anticorrosive protection of metal, surfaces, particularly metal surfaces containing zinc, provided with conversion layers. The decorative and functional properties of the surfaces are maintained or improved. Furthermore, the known problems with the use of compounds comprising chromium(VI) or with post-treatments with polymer dispersions are eliminated.
