ABSTRACT:
A process for removing, leaching, or dissolving ceramic cores used to maintain dimensional tolerances for internal passages during metal casting operations of hollow airfoils. The process is especially suited for dissolving porous ceramic cores, such as alumina, silica, alumina doped with oxides, and combinations thereof, that are used in internal passages in turbine airfoils during metal casting operations.
