Integrated ceramic/metallic components and methods of making same

摘要

Integrated ceramic/metallic components (50) and methods of making same are described herein. Embodiments of these integrated ceramic/metallic components comprise a metallic non-foam region (52); and a ceramic foam region (58) comprising a gradient porosity therein, wherein the ceramic foam region (58) and the metallic non-foam region (52) are integrally formed together to create the integrated ceramic/metallic component (50). Embodiments of these integrated ceramic/metallic components comprise a metallic region (52); and a single piece ceramic foam construction (58) comprising a plurality of ceramic foam regions (60, 70, 80) therein, each ceramic foam region comprising a predetermined pore size and a predetermined volume percent porosity, wherein the single piece ceramic foam construction (58) is integrally joined to the metallic region (52) to form the integrated ceramic/metallic component (50). These components may be utilized in gas turbine engines.
