Beschreibung
Zusammenfassung:	A corrosion inhibiting coating for metal objects as well as a method for applying a coating is described. Said coating comprising at least one cerium oxide and at least one polymer. The polymer comprises at least one cathecholic component covalently bound thereto, and the at least one polymer displays a net positive charge at a pH of 7. The material inventive coating is environmental friendly and does not display serious health risks. Further an excellent corrosion inhibition is obtained for metals, even for carbon steel. The corrosion the properties of a coated surface is comparable with those of stainless steel. La présente invention concerne un revêtement anticorrosion pour objets métalliques ainsi qu'un procédé d'application d'un revêtement. Ledit revêtement comprend au moins un oxyde de cérium et au moins un polymère. Le polymère comprend au moins un composant cathécholique auquel il est lié de façon covalente, et le ou les polymère(s) présente(nt) une charge positive nette à pH 7. Le revêtement de l'invention est écologique et ne présente aucun risque grave pour la santé. En outre, une excellente inhibition de la corrosion est obtenue pour les métaux, même pour l'acier au carbone. Les propriétés anticorrosion de la surface revêtue sont comparables à celles de l'acier inoxydable.
