Patent ID: 8342386

Claim:
An assembly comprising a gas turbine engine component having a substrate and a coating on the substrate, the coating being present on the substrate so as to define an outermost surface of the assembly, the coating comprising a braze material contacting a surface of the substrate, the braze material comprising: a first layer contacting the surface of the substrate; a second layer entirely separated from the surface of the substrate by the first layer and defining an outermost region of the coating relative to the component; a plurality of first particles of a metallic material having a melting point, a first quantity of the first particles being contained in the first layer and a second quantity of the first particles being contained in the second layer; and a plurality of second particles contained in the second layer but not in the first layer, the plurality of second particles comprising at least one nonmetallic material chosen from the group consisting of oxides, carbides, and nitrides of at least one metal, the nonmetallic material of the second particles being more susceptible to heating by microwave radiation than the metallic material of the first particles, and the nonmetallic material being present in the braze material in an amount sufficient to enable the first particles to completely melt when the first and second particles are subjected to heating by microwave radiation; wherein the outermost region of the coating defined by the second layer is exposed so that the second layer forms an outermost coating surface on the component following exposure thereof to the microwave radiation.
