Zusammenfassung:A barrier layer for an article according to an exemplary embodiment of this disclosure, among other possible things includes a bond coat comprising a matrix, diffusive particles disposed in the matrix, and gettering particles disposed in the matrix. The composition of the gettering particles is a reaction product of the chemical reaction of Equation 1 defined by Equation 2:Siw⁢Ox⁢Cy⁢Nz+ξ⁢O2=w⁢Si⁢O2+y⁢CO+z2⁢N2Equation⁢1ξ=2⁢w+y-x2Equation⁢2A barrier layer is also disclosed.
