Abstract: An article according to an exemplary embodiment of this disclosure, among other possible things includes a substrate and a barrier layer on the substrate. The barrier layer includes a bond coat comprising a matrix, diffusive particles disposed in the matrix, and gettering particles disposed in the matrix; a topcoat; and a porous interlayer disposed between the topcoat and the bond coat. The porous interlayer has a porosity that is greater than a porosity of the topcoat. A slurry composition for applying an interlayer to an article and method of applying a top coat to an article are also disclosed.

Abstract: A method of making a ceramic matrix composite according to an exemplary embodiment of this disclosure, among other possible things includes forming a ceramic matrix composite component by infiltrating an array of ceramic-based fibers with a ceramic-based matrix. The array of ceramic-based fibers forms a surface that includes gaps between adjacent ones of the fibers. The method also includes applying a paste including filler particles and filler matrix in a carrier fluid to the surface of the ceramic-based fibers that includes the gaps such that the paste fills the gaps and removing the carrier fluid to leave behind a filler including the filler particles and the filler matrix in the gaps. A ceramic matrix composite component is also disclosed.

Abstract: A method of applying a coating to a substrate includes forming a slurry by mixing elemental precursors of gettering particles, diffusive particles, matrix material, and a carrier fluid; applying the slurry to a substrate; and sintering the slurry to form a composite material. The sintering causes the elemental precursors to react with one another to form gettering particles. An article is also disclosed.
