摘要： A composite ceramic core that, in combination with a shell mold, is suitable for use in a casting process to produce metal alloy components. The core and casting process make use of a highly leachable interior layer in combination with an exterior layer that is less reactive than the interior layer in the presence of common alloying elements. The interior layer contains at least one hollow channel that allows a point of entry for a leaching solution, as well as exit for gaseous byproducts generated during the casting process.

摘要： A single-crystal seed, apparatus and process for producing a casting having a single-crystal (SX) microstructure. The seed has a geometry that includes a vertex capable of destabilizing an oxide film that forms at the interface between the seed and a molten metal during the casting process, and thereby promotes a continuous single-crystal grain growth and reduces grain misorientation defects that can initiate from the seed/metal interface.

摘要： A method for removing a chromide coating from the surface of a substrate is described. The coating is treated with a composition which includes an acid having the formula HxAF6, where “A” can be Si, Ge, Ti, Zr, Al, or Ga; and x is 1–6. An exemplary acid is hexafluorosilicic acid. The composition may also include a second acid, such as phosphoric acid or nitric acid. In some instances, a third acid is employed, such as hydrochloric acid. A related repair method for replacing a worn or damaged chromide coating is described. The coating is often applied to portions of turbine engine components made from superalloy materials.
