Summary:IMPROVED ADHESION OF THERMAL SPRAY COATINGS OVER A SMOOTH SURFACE OF THE DISCLOSURE A coated component is generally provided, along with methods of forming such a coating system. The coated component includes a substrate having a surface with a coating system thereon. The coating system may include a columnar thermal barrier coating (TBC) over the surface of the substrate, with the columnar TBC including surface-connected voids. An intermediate layer is over the columnar TBC layer. The intermediate layer has a surface opposite of the columnar TBC that is rougher than the surface of the columnar TBC. A second TBC is over the intermediate layer. [Figure 1]
