Abstract
An article includes a substrate and a bond coat disposed on the substrate. The bond coat includes a matrix, a plurality of gettering particles disposed in the matrix, a plurality of diffusive particles disposed in the matrix, a radiation-absorbing component disposed in the matrix, wherein the radiation-absorbing component is concentrated at an outer surface of the bond coat. An article and a method of protecting an article are also disclosed.
