Abstract
The invention relates to a method for producing an ultraphobic surface on aluminium as the supporting material and to the resulting surface and its use. According to said method, the surface of an aluminium support is anodized, especially by anodic oxidation, and/or electrochemically pickled in an acid solution with an alternating voltage, treated in hot water or water vapor at a temperature of 50 to 100° C., optionally coated with an adhesion promoter layer and then provided with a hydrophobic or especially oleophobic coating.
