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.

A method of forming a thermal barrier coating system on a surface of a component, the thermal barrier coating system comprising a thermal barrier coating that has columnar grains, the method comprising:
- introducing the component into a coating chamber, wherein a first ceramic source material and a second ceramic source material are positioned within the coating chamber of a physical vapor deposition apparatus;
- directing an energy source in the form of a laser onto the first ceramic source material to vaporize the first ceramic source material to deposit a first layer on the component;
- and
- alternating the energy source between the first ceramic source material and the second ceramic source material to form a blended layer on the first layer, wherein the blended layer is formed from vapors from the first ceramic source material and the second ceramic source material, wherein the first ceramic source material and the second ceramic source material are different materials.
