Abstract

Die Erfindung betrifft einen Wärmetauscher, insbesondere Abgaswärmetauscher, mit mindestens einer von einem Medium, insbesondere von Abgas, beaufschlagten Fläche aus Metall, insbesondere aus Aluminium oder Edelstahl, die mit einer Beschichtung versehen ist.The invention relates to a heat exchanger, in particular exhaust gas heat exchanger, with at least one of a medium, in particular of exhaust gas, acted upon surface of metal, in particular of aluminum or stainless steel, which is provided with a coating.

Die Beschichtung ist durch eine hohe Temperatur, insbesondere eine erstmalige hohe Betriebstemperatur, in eine korrosionsbeständige, teilkeramische und/oder schwer benetzbare, insbesondere oleophobe, Schutzschicht umsetzbar und/oder umgesetzt.The coating can be converted and / or converted into a corrosion-resistant, partially ceramic and / or difficultly wettable, in particular oleophobic, protective layer by a high temperature, in particular a first-time high operating temperature.
