Abstract

Durch gezielte Auswahl der Zugaben von Oxiden zu Zirkonoxid wird ein keramisches Material bereitgestellt, insbesondere für die Verwendung eines Schichtsystems, das einen hohen Sinterwiderstand, hohe Dehnungstoleranz und geringe Wärmeleitfähigkeit aufweist.

Description

Keramisches Material auf der Basis von Zirkonoxid mit weiteren Oxiden
Die Erfindung betrifft ein keramisches Material, was insbe sondere zur Verwendung von keramischen Schichten verwendet werden kann. Die Verwendung von Zirkonoxid-basierten kerami schen Materialien sind aus der Verwendung für keramische Hit zeschilde aus Vollmaterial oder keramische Schutzschichten auf Turbinenschaufeln oder Hochtemperaturbauteilen bekannt. Dabei ist es wichtig, dass ein hoher Sinterwiderstand, eine Phasenstabilität, eine hohe Bruchzähigkeit und hohe Dehnungs toleranz gegeben ist.
Es ist daher Aufgabe der Erfindung bestehende Materialsysteme zu verbessern.
Die Aufgabe wird gelöst durch ein keramisches Material gemäß Anspruch 1.
In den weiteren Unteransprüchen sind weitere Vorteile aufge listet, die beliebig miteinander kombiniert werden können, um weitere Vorteile zu erzielen.
Es zeigen die Figuren 1, 2 schematisch Schichtsysteme aus einem keramischen Material.
Es wird vorgeschlagen, 4mol% bis 30mol% Ceroxid (CeCg) , Cal ciumoxid (CaO) und/oder Magnesiumoxid (MgO) als weitere op tionale Oxide und als Basisoxid 2mol% bis 30mol% Erbiumoxid (Er203) und/oder Ytterbiumoxid (Yb203) zu verwenden.
Eine solche keramische Schicht hat insbesondere eine Schicht dicke von 20ym bis lOOOym, insbesondere bis 2000ym und kann vorzugsweise mittels thermischem Spritzen, insbesondere APS oder EB-PVD hergestellt werden. Das keramische Material hat einen hohen Sinterwiderstand, eine hohe Dehnungstoleranz und hohe Bruchzähigkeit sowie weist es eine geringere Wärmeleitfähigkeit auf.
Ausführungsbeispiele :
ZrO2 +
- Er2<D3 + Yb203
- Yb203
- Er2<D3 (3 Varianten mit Basisoxiden)
Zu diesen 3 Varianten können jeweils
- Ce02
- CaO
- MgO
- Ce02 + CaO
- Ce02 + MgO
- CaO + MgO
- Ce02 + CaO + MgO
als weitere Oxide hinzugegeben werden, also insgesamt 21 Varianten .
Figur 1 zeigt ein erfindungsgemäßes Schichtsystem 1.
Das Schichtsystem 1 weist ein Substrat 4 auf. Das Substrat 4 ist insbesondere eine Nickelbasis-Superlegierung oder stellt ein CMC-Substrat dar.
Auf dem Substrat 4 ist eine Anbindungsschicht vorhanden, die insbesondere bei einer Nickelbasis-Superlegierung eine
NiCoCrAlY-basierte Legierung oder eine Aluminid- bzw. eine Platin-Aluminidschicht darstellt .
Auf dieser metallischen Haftvermittlerschicht bildet sich während des Beschichtens oder während des Betriebs eine Oxid schicht (TGO) aus.
Auf dieser Oxidschicht (TGO) oder auf der metallischen Haft vermittlerschicht 7 ist eine keramische Schicht gemäß dem keramischen Material aufgebracht. Im Falle eines keramischen Substrats 4 (CMC) ist gegebenen falls keine Anbindungsschicht für die keramische Schicht 10 notwendig . In Figur 2 ist eine Variante gezeigt, bei der das Schichtsys tem 1 ' bezüglich der keramischen Schutzschicht zweilagig aus gebildet ist. Bezüglich des Substrats und/oder der Substrat materialien der Anbindungsschicht 7 gilt vergleichbares bei Figur 1. Jedoch bildet die äußerste keramische Schicht 16 hier das keramische Material der Erfindung.
Unter dieser keramischen Schicht 16 ist eine keramische An bindungsschicht 13 vorhanden zwecks Anpassung von thermischen Ausdehnungskoeffizienten oder Anpassung der Porositäten.
