    摘要: Methods for rapid prototype casting metal components, wherein the metal components are cast in a secondary ceramic mold, the secondary ceramic mold is cast in a primary mold, and the primary mold is formed by rapid prototyping or rapid manufacturing. The secondary ceramic mold may comprise a one-piece integral shell and core(s), and the metal components may have at least one hollow portion or void therein, such as a hollow airfoil for a gas turbine engine.

    摘要: A component for a turbine engine component includes a ceramic substrate having a surface, an environmental barrier layer bonded to the substrate surface, and an impact-resistance layer bonded to the environmental barrier layer, the impact-resistance layer having a melting point higher than about 2700° F., and further having a between about 10 and about 30% porosity. The impact-resistance layer, environmental barrier layer, and interfaces at which the environmental layer is bound to the substrate surface and the impact-resistance layer are more readily shearable than the substrate. A method for protecting a turbine engine component from environmental and particle impact-related damage includes the steps of coating a substrate surface with the environmental barrier layer, and coating the environmental barrier layer with the impact-resistance layer.
