Abstract
Durch die Verwendung einer raueren keramischen Wärmedämmschicht kann eine äußere keramische Wärmedämmschicht besser angebunden werden, so dass dickere keramische Schichten hergestellt werden können, die eine hohe Dehnungstoleranz mit verbesserten bruchmechanischen Eigenschaften aufweist. By using a rougher ceramic thermal barrier coating, an outer ceramic thermal barrier coating can be better bonded so that thicker ceramic layers can be made having high elongation tolerance with improved fracture mechanical properties.
Description
Die Erfindung betrifft ein keramisches Wärmedämmschichtsystem, das dicker ausgebildet ist, um den Einsatz bei höheren Temperaturen zu ermöglichen. The invention relates to a ceramic thermal barrier coating system which is made thicker to allow use at higher temperatures.
Im Heißgaspfad von Turbinen befinden sich Bauteile, die zur Erniedrigung der Metalltemperatur mit keramischen Wärmedämmschichten (TBC) aus teilstabilisiertem Zirkonoxid oder Pyrochlor beschichtet sind. Hochporöse, 1–2mm dicke Wärmedämmschichten haben den Nachteil, dass die Bruchzähigkeit im Bereich der metallischen Aluminiumschicht gering ist. Ein Versagen wird oft bei ca. 50µm oberhalb der metallischen Haftvermittlerschicht beobachtet. In the hot gas path of turbines are components that are coated to lower the metal temperature with ceramic thermal barrier coatings (TBC) of partially stabilized zirconia or pyrochlore. Highly porous, 1-2mm thick thermal barrier coatings have the disadvantage that the fracture toughness in the region of the metallic aluminum layer is low. Failure is often observed at about 50μm above the metallic primer layer.
Sogenannte „microcracked“-Schichten haben den Nachteil der Temperaturbegrenzung mit 1523K. So-called "microcracked" layers have the disadvantage of temperature limitation with 1523K.
Es gilt daher eine Schicht aufzuzeigen, die im unteren Bereich eine hohe Bruchzähigkeit hat und im oberen Bereich eine hohe Duktilität mit hoher erlaubter Oberflächentemperatur (1523K–1723K). It is therefore necessary to show a layer which has a high fracture toughness in the lower region and a high ductility in the upper region with a high permissible surface temperature (1523K-1723K).
Es wurde bis jetzt nur immer eine hochporöse Schicht oder „microcracked“-Schicht mit Überkühlung eingesetzt, so dass die Grenzflächentemperatur MCrAlY/TBC sehr niedrig ist. Die erlaubte Oberflächentemperatur war auf 1523K begrenzt. Until now, only a highly porous layer or "microcracked" layer with overcooling has been used so that the interfacial temperature MCrAlY / TBC is very low. The allowed surface temperature was limited to 1523K.
Es ist daher Aufgabe der Erfindung ein Wärmedämmschichtsystem aufzuzeigen, das die oben genannten Probleme löst. It is therefore an object of the invention to provide a thermal barrier coating system that solves the above problems.
Die Aufgabe wird gelöst durch ein Wärmedämmschichtsystem gemäß Anspruch 1. The object is achieved by a thermal barrier coating system according to claim 1.
In den Unteransprüchen sind weitere vorteilhafte Maßnahmen aufgelistet, die beliebig miteinander kombiniert werden können, um weitere Vorteile zu erzielen. In the dependent claims further advantageous measures are listed, which can be combined with each other in order to achieve further advantages.

Ebenso sind Mischungen von Gadoliniumzirkonat, Zirkonoxid und/oder Hafniumoxid sowie Zirkonate oder Hafnate insbesondere auf der Basis Gadolinium (Gd) möglich. Likewise, mixtures of gadolinium zirconate, zirconium oxide and / or hafnium oxide and zirconates or hafnates, in particular based on gadolinium (Gd), are possible.

Die Dicke der äußeren keramischen Wärmedämmschicht
Da die Bruchzähigkeit zwischen der Zirkonoxid-basierten Schicht (PSZ) und der Gadoliniumoxid-basierten Schicht (GZO) einen Schwachpunkt darstellen kann, kann die Anbindung zwischen GZO und PSZ verbessert werden. Dies ist möglich, indem vorzugsweise zwischen PSZ und GZO eine raue Lage als keramische Zwischenschicht
Diese Rauigkeit der keramischen Zwischenschicht soll zwischen Ra= 6µm und Ra = 12µm variieren. Damit würden diese drei Schichten eine hohe Dehnungstoleranz mit verbesserten bruchmechanischen Eigenschaften aufweisen. This roughness of the ceramic intermediate layer should vary between Ra = 6μm and Ra = 12μm. Thus, these three layers would have a high elongation tolerance with improved fracture mechanical properties.
Der erfinderische Schritt liegt dann in der optimalen Verbindung zweier Schichtsysteme mit guter Dehnungstoleranz und sehr guten bruchmechanischen Eigenschaften der Haftungsschicht und verbesserter Anbindung dieser Schichten, insbesondere durch Einstellung einer Schicht mit guter Interfacerauigkeit. The inventive step then lies in the optimal combination of two layer systems with good elongation tolerance and very good fracture-mechanical properties of the adhesion layer and improved bonding of these layers, in particular by setting a layer with good interface accuracy.
Die Oberfläche der metallischen Haftvermittlerschicht kann auch eine durch Laser oder Wasserstrahlbearbeitung strukturierte Oberfläche aufweisen. Durch Verwendung der DVS-Schicht kann auch noch die Erosionsrate reduziert werden. Diese Erfindung erlaubt durch Variation der Einzelschichtstrukturen eine Optimierung der Eigenschaften mit Anpassung an den benötigten Belastungszustand in der Maschine. The surface of the metallic adhesion promoter layer may also have a surface structured by laser or water jet machining. By using the DVS layer also the erosion rate can be reduced. By varying the single-layer structures, this invention permits optimization of the properties with adaptation to the required load state in the machine.
