Abstract: A method for manufacturing a water- and ice-repellent surface on a metallic substrate is disclosed, comprising the steps of a) providing a metallic substrate, b) polishing the metallic substrate, c) contacting of at least a part of the metallic substrate with an electrolyte solution, d) anodizing the metallic substrate of step c) for producing a nanoporous layer on the substrate surface, and e) applying a hydrophobic coating on the nanoporous layer. Thereby the accretion of ice particularly on surfaces of aircraft exposed to a flow is reduced in comparison with the prior art.
