摘要： A gas turbine engine article includes a substrate and a bond coating that covers at least a portion of the substrate with a step formed in at least one of the substrate and the bond coating. A thermally insulating topcoat is disposed on the bond coating. The thermally insulating topcoat includes a first topcoat portion separated by at least one fault that extends through the thermally insulating topcoat from a second topcoat portion.

摘要： An apparatus for manufacturing a powder has: a chamber; a temperature control system for the chamber interior; and a conveyor within the chamber. First, second, and third powder sources supply respective first, second, and third powders along respective first, second, and third powder flowpaths. The second and third flowpaths merge with the first flowpath along the conveyor. The apparatus comprises a vaporizer for vaporizing a solvent to be delivered to the second and third powders along the second and third powder flowpaths.

摘要： A component for a gas turbine engine includes a surface adjacent a flow of hot gases. A plurality of cavities is in a portion of the surface. The plurality of cavities have a first group of cavities with a first cross-section and a second group of cavities with a second cross-section different from the first cross-section. The first and second groups of cavities are arranged such that there is no straight line across the portion of the surface that does not intersect one of the plurality of cavities. A thermal barrier coating is over the surface and fills each of the plurality of cavities.

摘要： A method includes forming a ceramic member that has a plurality of closed pores within a ceramic matrix. The forming includes compacting a ceramic powder to form intra-particle pores between particles of the ceramic powder, and sintering the compacted ceramic powder to cause diffusion of the ceramic powder and formation of the ceramic matrix. The diffusion does not fill the intra-particle pores and leaves the closed pores.

摘要： A method for coating a substrate with a ceramic coating, includes the steps of: applying a bond coat material to a surface of a substrate to form a bond coat on the surface; and applying a ceramic coat over the bond coat, wherein the step of applying the bond coat material produces a bond coat having a lower elastic modulus as compared to a conventionally applied bond coat.

摘要： A method of manufacturing a gas turbine engine air seal comprising forming at least one MAX phase particle. The method includes coating the at least one MAX phase particle with a metallic shell. The method includes applying the at least one MAX phase metallic coated particle to a surface of a substrate of the air seal to form an abradable layer of a MAXMET composite abradable material from the at least on MAX phase metallic coated particle.
