Abstract

Durch eine neue Zusammensetzung mit geringerem Kobaltgehalt einer MCrAlY Legierung wird eine Haftvermittlerschicht hergestellt, die die TGO sehr langsam wachsen lässt. Die nickelbasierte Legierung, zumindest aufweisend (in Gew.-%): Kobalt (Co) 0,2% - 5,0%, Chrom (Cr) 14,0% - 20,0%; Aluminium (Al) 6,0% - 8,0%; Tantal (Ta) 1,0% - 3,0%; Yttrium (Y) 0,3% - 0,6% Nickel (Ni) 70,0% - 75,0%.

Description

Beschreibung
Legierung, Pulver, duktile gamma ' -Haftvermittlerschicht und Bauteil
Die Erfindung betrifft eine Legierung, ein Pulver, eine duktile Haftvermittlerschicht sowie ein Bauteil .
Das thermomechanische Verhalten von metallischen Haftvermittlerschichten auf Substraten hat einen direkten Einfluss auf die Leistungsfähigkeit keramischer Wärmedämmschichtsysteme , welche bei Turbinenbauteilen ein Substrat auf Nickel- oder Kobaltbasis , der Haftvermittlerschicht und zumindest einer keramischen Schicht (TBC) darüber aufweisen .
Diese metallischen Haftvermittlerschichten haben mehrere strenge Kriterien zu erfüllen wie Oxidationsschutz , Langzeitwärmestabilität, Festigkeit und Duktilität .
Insbesondere für Wasserstof fturbinen besteht eine andere Anforderung an das Wärmedämmschichtsystem .
Es ist daher Aufgabe der Erfindung oben genanntes Problem zu lösen .
Die Aufgabe wird gelöst durch eine Legierung gemäß Anspruch 1 , ein Pulver gemäß Anspruch 2 , eine Schicht gemäß Anspruch 3 und ein Bauteil gemäß Anspruch 4 .
In den Unteransprüchen sind weitere vorteilhafte Maßnahmen aufgelistet, die beliebig miteinander kombiniert werden können, um weitere Vorteile zu erzielen . Die Erfindung weist eine nickelbasierte Legierung auf, insbesondere besteht sie aus (in Gew. -%) :
Kobalt (Co) 0,2% - 5,0%, insbesondere 1,0% - 4%; Chrom (Cr) 14,0% - 20,0% insbesondere 16,0% - 18,0% Aluminium (Al) 6,0% — 8,0%, insbesondere 7,0%; Tantal (Ta) 1,0% - 3,0%, insbesondere 2,0%; Yttrium (Y) 0,3% - 0,6%; Nickel (Ni) 64,0% - 79,0% insbesondere 70,0% - 75,0%
Auffällig und notwendig ist der geringe Gehalt an Kobalt (Co) .
Verunreinigungen in der Legierung sind immer vorhanden.
Die Y' -haltige Haftvermittlerschicht verlangsamt das Wachstum der Aluminiumoxidschicht (TGO) und kann dadurch die thermalzyklische Lebensdauer einer darüberliegenden keramischen Schicht (TBC) oder Schichtsystem (Substrat + NiCoCrAl + optional TBC) verbessern.
Ein Pulver aus der Legierung kann optional Binder andere Partikel wie insbesondere keramische oder Refraktär-Partikel aufweisen .
Ein Bauteil, insbesondere für eine Wasserstoff betriebene Gasturbine, weist ein Substrat auf.
Das Substrat weist vorzugsweise eine nickel- oder kobaltbasierte Legierung auf.
Darauf wird die erfindungsgemäße Legierung auf der Basis NiCoCrAlYTa aufgebracht. Dies kann erfolgen mittels Methoden aus dem Stand der Technik erfolgen, insbesondere mittels HVOF und APS . Ebenso denkbar sind zweilagige NiCoCrAlY Schutzschichten, bei denen die erfindungsgemäße Legierung vorzugsweise den äußeren Teil bildet .
Darauf bildet sich im Betrieb oder schon während der kerami- sehen Beschichtung eine TGO .
Eine keramische Beschichtung (TBC) auf der NiCoCrAlYTa kann einlagig oder zweilagig ausgebildet sein . Vorzugsweise stellt stabilisiertes Zirkonoxid die Basis für die TBC dar .
