Abstract
The present invention relates to a process for vapor-depositing zirconium dioxide on ceramic or metallic substrates, and the heat-insulating layers obtainable by such process.
Claims14
A ceramic heat-insulating layer for a ceramic or metallic substrate, the layer comprising a plurality of club shaped columns which coat the substrate, wherein the columns comprise zirconium dioxide.
A heat-insulating layer for a ceramic or metallic substrate, the layer comprising a plurality of club shaped columns which coat the substrate, wherein the layer is formed by a process of vapor-depositing zirconium dioxide, optionally doped with rare-earth metal oxides or mixtures of such oxides, on a ceramic or metallic substrate.
