Abstract:
Die vorliegende Erfindung bezieht sich auf eine tiefschwarze Beschichtung mit Beständigkeit gegenüber Verschleiss, wobei auf eine Komponente zunächst eine DLC-Schicht mit hoher Härte aufgebracht wird und auf diese DLC-Schicht Gradientenschicht aufgebracht wird, deren Dichte in Richtung Oberfläche abnimmt. Durch den dadurch in der Gradientenschicht entstehenden Brechungsindexverlauf wirkt die Gradientenschicht als reflexmindernde Schicht.

Abstract:
An article may include a superalloy substrate and a calcia-magnesia-alumina-silicate (CMAS)-resistant thermal barrier coating (TBC) layer overlying the superalloy substrate. In some embodiments, the CMAS-resistant TBC layer includes between about 50 wt. % and about 90 wt. % of a TBC composition and between about 10 wt. % and about 50 wt. % of a CMAS-resistant composition. In some examples, the TBC composition includes at least one of yttria-stabilized zirconia, yttria-stabilized hafnia, zirconia stabilized with at least three rare earth oxides, or hafnia stabilized with at least three rare earth oxides. In some examples, the CMAS-resistant composition includes alumina, silica, and an oxide of at least one of Sc, Y, La, Ce, Pr, Nd, Pm, Sm, Eu, Gd, Yb, Dy, Ho, Er, Tm, Tb, or Lu.
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.
