Abstract: The present disclosure generally relates to casting molds including a casting core comprising an outer shell mold surrounding at least a portion of a casting core and a casting core comprising a second metal skin layer around a first metal component. In one aspect, at least one portion of the first metal component may be exposed on a surface of the outer shell mold. In another aspect, the outer shell mold may be configured to define a cavity in the casting core when the first metal component is removed and the second metal skin layer is not removed.

Abstract: A hot gas path component for an engine may generally include a substrate extending between an outer surface and an inner surface opposite the outer surface. The outer surface may be configured to be exposed to a hot gas path of the engine. In addition, the substrate may be formed from a non-metallic composite material. The hot gas path component may also include a thermal coating disposed on the inner surface of the substrate. The thermal coating may be applied to the inner surface so as to have a non-uniform distribution along at least a portion of the inner surface, wherein the non-uniform distribution provides for change in a thermal gradient experienced across the hot gas path component between the outer and inner surfaces of the substrate.
Abstract translation: 用于发动机的热气体通路部件通常可以包括在外表面和与外表面相对的内表面之间延伸的基板。 外表面可以被配置为暴露于发动机的热气路径。 此外，基板可以由非金属复合材料形成。 热气体路径部件还可以包括设置在基板的内表面上的热涂层。 热涂层可以施加到内表面，使得沿着内表面的至少一部分具有不均匀的分布，其中非均匀分布提供了跨越热气路径部件之间经历的热梯度的变化， 衬底的外表面和内表面。
