Abstract (en)

[origin: EP2650062A2] A composite ceramic core (12) that, in combination with a shell mold (22), is suitable for use in a casting process to produce metal alloy components. The core (12) and casting process make use of a highly leachable interior layer (14) in combination with an exterior layer (16) that is less reactive than the interior layer (14) in the presence of common alloying elements. The interior layer (14) 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.
