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