Abstract
Official abstract text for this publication.
The present invention relates to a protective layer against CMAS, to a CMAS-resistant article comprising the protective layer according to the invention, and to a process for preparing a corresponding article.
First claim
Opening claim text (preview).
The invention claimed is: 1. A protective layer against CMAS, characterized in that said protective layer consists of oxides of iron, yttrium and silicon. 2. The protective layer according to claim 1 , characterized in that the layer thickness of the protective layer is from 10 μm to 200 μm. 3. A CMAS-resistant article, comprising: a basic structure made of a refractory material with a surface, a first coating on this surface, and a protective layer consisting of oxides of iron, yttrium and silicon that has been applied to this first coating. 4. The article according to claim 3 , characterized by being a turbine or an inliner on the combustion chamber. 5. The article according to claim 3 , characterized in that said refractory material comprises an Ni-based superalloy or SiC. 6. The article according to claim 3 , characterized in that said first coating is a thermal insulation layer (TBC) or environmental barrier coating (EBC). 7. A process for preparing an article according to claim 3 , characterized in that the protective layer is applied to the first coating by means of sputter technology or PVD.
