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.
