Abstract: PROBLEM TO BE SOLVED: To provide a superalloy article having a thermal barrier coating film. SOLUTION: The article comprises a superalloy substrate, an adherent alumina layer on the substrate, and a ceramic, thermally insulating layer on the alumina layer. The ceramic layer has an overall thickness and comprises relatively strain tolerant columnar grain ceramic on the alumina layer and relatively more thermally insulating ceramic 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 be constituted of a material 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. COPYRIGHT: (C)2003,JPO

Abstract: A refractory metal core for use in a casting system has a coating for providing oxidation resistance during shell fire and protection against reaction/dissolution during casting. In a first embodiment, the coating comprises at least one oxide and a silicon containing material. In a second embodiment, the coating comprises an oxide selected from the group consisting of calcia, magnesia, alumina, zirconia, chromia, yttria, silica, hafnia, and mixtures thereof. In a third embodiment, the coating comprises a nitride selected from the group consisting of silicon nitride, sialon, titanium nitride, and mixtures thereof. Other coating embodiments are described in the disclosure.

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.
