HEAT SHIELD HAVING AN OUTERMOST YTTRIUM OXIDE COATING, PRODUCTION METHOD AND PRODUCT
The corrosion and erosion resistance of ceramic heat shield elements is improved by the use of yttrium oxide on aluminum oxide as a layer or substrate material is provided. A heat is disclosed having aluminum oxide in the substrate or as a layer on a substrate, wherein yttrium oxide, particularly only yttrium oxide, is present as the outermost layer, particularly directly on the aluminum oxide.
