Abstract
An article includes a substrate and an adhesion layer overlying the substrate. The adhesion layer includes a first phase including particles, and a second phase including braze alloy that bonds the particles to the substrate. The article further includes a ceramic layer overlying the adhesion layer. In one embodiment, the ceramic layer is a thermal barrier coating (TBC), formed of stabilized zirconia (ZrO2).
