Abstract (en)

A coated component (10) is generally provided, along with methods of forming such a coating system (20). The coated component (10) includes a substrate having a surface (25,27) with a coating system (20) thereon. The coating system (20) may include a columnar thermal barrier coating (TBC) (24) over the surface (25,27) of the substrate, with the columnar TBC (24) including surface-connected voids (30). An intermediate layer (26) is over the columnar TBC layer. The intermediate layer (26) has a surface (25,27) opposite of the columnar TBC (24) that is rougher than the surface (25,27) of the columnar TBC (24). A second TBC (28) is over the intermediate layer (26).
