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.
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.
