Abstract: A superalloy article is disclosed having a thermal barrier coating. The article comprises a superalloy substrate (18), an adherent alumina layer (20) on the substrate, and a ceramic, thermally insulating layer (22) on the alumina layer. The ceramic layer has an overall thickness and comprises a relatively strain tolerant, columnar grain ceramic (24) on the alumina layer and relatively more thermally insulating ceramic (26) on the columnar grain ceramic. The alumina layer may be formed using an alumina forming layer such as an overlay or aluminide bond coat, or the superalloy may comprise a material that is capable of forming an alumina layer. The ceramic layers may be formed of a stabilized zirconia or other suitable material, and may have the same or different compositions.

Abstract: A turbine component has a substrate formed from a ceramic material selected from the group consisting of a monolithic ceramic material and a composite ceramic material and a thermal barrier coating bonded to the substrate. In one embodiment, the ceramic material forming the substrate is selected from the group of silicon nitride and self-reinforced silicon nitride. In another embodiment, the ceramic material forming the substrate is selected from the group consisting of a silicon carbide-silicon carbide material and a carbon-carbon material. At least one bond coat layer may be interposed between the substrate and the thermal barrier coating.

Abstract: Methods of producing layered ceramic coatings in which some layers contain porosity are described, as are the coatings produced. The different layers are applied at different temperature conditions by periodically inserting a heat blocking shield between the heat source and either the'evaporation source and/or an external heater. As applied, some of the layers have a Zone I structure and some have a Zone II type structure. Heat treatment may be used to increase the porosity in the Zone I structure layers.
