Abstract (en)
[origin: WO2015135521A1] The invention relates to a method for producing a water-repellent and ice-repellent surface on a metal substrate, comprising the steps of a) providing a metal substrate, b) polishing the metal substrate, c) bringing at least a part of the metal substrate surface into contact with an electrolyte solution, d) anodising the metal substrate from step c) in order to produce a nanoporous layer on the substrate surface, and e) applying a hydrophobic coating to the nanoporous layer. Thus the accumulation of ice, in particular on aircraft surfaces which are subject to an air flow, can be reduced in comparison with the prior art.
