<p>The porous ceramic layer system comprises a substrate, a metallic bonding layer (7) on the substrate, an oxide layer on the bonding layer or on the substrate, an inner ceramic layer (10) with a porosity of 11-12%, and an outer ceramic layer (13) with a porosity of 16-18% on the inner ceramic layer. The material of the ceramic layers is different. The outer ceramic layer comprises a pyrochlore structure. The inner ceramic layer is 10% thinner than the outer ceramic layer.</p> |
