Abstract

Die Erfindung betrifft eine Verwendung einer keramischen Schicht (12) mit Partikeln (16), die an der Kondensationsfläche (13) die Benetzbarkeit durch Wasser (W) herabsetzen bei einem Kondensatorbauteil (11) für Wasserdampf, wie dieses beispielsweise in der Kraftfahrttechnik Verwendung findet. Weiterhin betrifft die Erfindung ein Verfahren zum Erzeugen einer solchen Schicht, wobei die Partikel (16) sowie Vorstufen der Keramik in einem Lösungsmittel gelöst, auf die Innenwandungen des Kondensatorrohres (11) aufgebracht und durch eine Wärmebehandlung in eine Keramik umgewandelt werden. Es hat sich gezeigt, dass derartig erzeugte Beschichtungen auch über eine größere Betriebsdauer des Kondensatorbauteils (11) hinweg die Benetzbarkeit der Kondensatorfläche (13) herabsetzen und damit den Wirkungsgrad der Kondensation vorteilhaft erhöhen.
