Abstract: An article includes a ceramic-based substrate and a barrier layer on the ceramic-based substrate. The barrier layer includes a matrix phase and gettering particles in the matrix phase. The gettering particles with an aspect ratio greater than one are aligned such that a maximum dimension of the gettering particles extends along an axis that is generally parallel to the substrate. The barrier layer includes a dispersion of diffusive particles in the matrix phase. A composite material and a method of applying a barrier layer to a substrate are also disclosed.

Abstract: An example article according to the present disclosure includes, among other possible things, a metallic substrate, and a bond coat on the metallic substrate. The bond coat includes a matrix phase, gettering particles in the matrix phase, wherein the gettering particles are reactive with oxidants, and a dispersion of matrix modifier particles in the matrix phase. The example article also includes a diffusion barrier between the bond coat and the metallic substrate, wherein the diffusion barrier is configured to inhibit diffusion of components from the bond coat into the metallic substrate. An example composite material and method of applying a barrier to a substrate are also disclosed.

Abstract: A method for forming a self-healing ceramic matrix composite (CMC) component includes depositing a first self-healing particulate material in a first region of a CMC preform of the CMC component and depositing a second self-healing particulate material having a different chemical composition than the first self-healing particulate material in a second region of the CMC preform distinct from the first region.

Abstract: An airfoil includes an airfoil wall that defines a leading end, a trailing end, and suction and pressure sides that join the leading end and the trailing end. The airfoil wall is formed of a silicon-containing ceramic. A first environmental barrier topcoat is disposed on the suction side of the airfoil wall, and a second, different environmental barrier topcoat is disposed on the pressure side of the airfoil wall. The first topcoat is vaporization-resistant and the second topcoat is resistant to calcium-magnesium-aluminosilicate.

Abstract: A gas turbine engine article includes a silicon-containing ceramic substrate and an environmental barrier coating (EBC) system disposed on the substrate. The EBC system includes, from the substrate, a dense bond coat layer, a porous bond coat layer, and a topcoat layer in contact with the porous bond coat layer. The dense bond coat layer and the porous bond coat layer each include a silica matrix and oxygen-scavenging gas-evolution particles dispersed through the silica matrix. The porous bond coat layer includes engineered pores.
