    摘要: A structure includes a cooled article having an open-cell solid foam of ceramic or metal cell walls with a porous interconnected intracellular volume therebetween. A source of a pressurized gas is in communication with a source region of the cooled article. The source of the pressurized gas includes a gas plenum in gaseous communication with the source region, and a compressor having a compressed gas output in gaseous communication with the gas plenum. Gas flows from the source of the pressurized gas through the porous intracellular volume, to cool the cooled article.

    摘要: A turbine blade has an airfoil section with a root end and a tip end, and an attachment at the root end of the airfoil section. A blade tip seal is joined to the tip end of the airfoil section. The blade tip seal is formed as an open-cell solid aluminum oxide foam made of aluminum oxide cell walls having intracellular volume therebetween. The blade tip seal has a blade interface region adjacent to the tip end of the airfoil section. The blade interface region is formed of the aluminum oxide foam and a nickel-base alloy within the intracellular volume. The blade tip seal also has a contact region remote from the blade interface region and comprising the aluminum foam wherein the intracellular volume is porosity.

    摘要: A substrate is protected by first providing the substrate, and applying a ceramic coating overlying and bonded to the substrate. The ceramic coating is formed of an open-cell solid foam of ceramic cell walls having an interconnected intracellular volume therebetween which is filled at least in part with a metallic alloy. The ceramic coating has an exposed surface remote from the substrate. The exposed surface of the ceramic coating is heated to an exposure temperature such that at least some of the metallic alloy is lost from the intracellular volume.

    摘要: A protective structure includes a substrate made of a nickel-base superalloy component of a gas turbine engine, and a ceramic thermal barrier coating overlying and bonded to the substrate. The ceramic coating is an open-cell solid foam of aluminum oxide ceramic cell walls having a porous interconnected intracellular volume therebetween. The ceramic coating is prepared by depositing a precursor material onto the surface of the substrate. The precursor material includes a sacrificial ceramic, typically silicon dioxide, and a reactive metal, typically aluminum, which is reactive with the sacrificial ceramic to form an open-celled ceramic foam. The sacrificial ceramic and the reactive metal are reacted together to form ceramic cell walls of an oxidized ceramic of the reactive metal, preferably aluminum oxide, and an interconnected intracellular volume therebetween filled with an intracellular metal. The intracellular metal is thereafter removed to leave a porous intracellular volume.
