Abstract: A method of forming a cast component and a method of forming a casting mold is generally provided. The method is performed by plugging or covering an opening in a ceramic core-shell mold. The ceramic core-shell mold includes at least a first core portion, a first shell portion, and at least one first cavity between the core portion and the first shell portion. The core-shell mold may be manufactured using an additive manufacturing process. At least a portion of the ceramic core-shell mold and the plug or cover is coated with a second ceramic material.

Abstract: Methods are provided for forming a thermal barrier coating system on a surface of a component. The method can include introducing the component into a coating chamber, where a first ceramic source material and a second ceramic source material are positioned within the coating chamber of a physical vapor deposition apparatus. An energy source is directed onto the first ceramic source material to vaporize the first ceramic source material to deposit a first layer on the component. The energy source is alternated between the first ceramic source material and the second ceramic source material to form a blended layer on the first layer.

Abstract: 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.

Abstract: A coating system disposed on a surface of a substrate is provided. The coating system may include a bond coating layer on the surface of the substrate, a dense TBC layer on the bond coating layer, and a columnar TBC layer on the dense TBC layer, with the columnar TBC layer defines a plurality of elongated surface-connected voids. The dense TBC layer generally includes a ceramic material and has a porosity of about 15% or less. A method is also provided for forming a coating system on a surface of a substrate.
