Abstract: A ceramic material having particular utility as a thermal insulating or thermal barrier coating on metallic substrates is provided. The ceramic material broadly comprises at least one oxide and the balance comprising a first oxide selected from the group consisting of zirconia, ceria, and hafnia. The at least one has a formula A2O3 where A is selected from the group consisting of La, Pr, Nd, Sm, Eu, Tb, In, Sc, Y, Dy, Ho, Er, Tm, Yb, Lu, and mixtures thereof. The present invention also broadly relates to an article having a metal substrate and a thermal barrier coating as discussed above.

Abstract: A method for reducing thermal conductivity in thermal barrier coatings (TBC) through the incorporation of porosity comprising the steps of depositing a mixture comprising a TBC matrix (13) and a fugitive material (11) upon a part to form a layer, and heating the layer at a temperature and for a duration sufficient to liberate a portion of the fugitive material to form a porous network.

Abstract: A thermal barrier coating system for a superalloy substrate is disclosed. T he superalloy is preferably of the type that is capable of forming an adherent alumina layer. A bond coat is applied to a local area of the substrate, so that a portion of the substrate remains exposed. The localized area is defined to be the area(s) a t which a TBC typically fails first, e.g., the leading and trailing edges of an airfoi l, or other area. An alumina layer is formed on the remaining portion of the substrate, and al so on the bond coat. A ceramic layer is then applied on the alumina layer. Even if the ceramic material is removed, the localized bond coat remains, and reduces the rate a t which the underlying substrate oxidizes. A coated article is also disclosed, as is a system that utilizes a conventional superalloy and aluminide coating with the localized bond coat.

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: 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.
