METHOD FOR MANUFACTURING AN INTEGRATED CASTING CORE-SHELL STRUCTURE AND USE THEREOF

The present disclosure generally relates to integrated core-shell investment casting molds that provide a filament structure corresponding to a cooling hole pattern in the surface of the turbine blade or stator vane, which provide a leaching pathway for the core portion after metal casting. The inve...

Zusammenfassung:	The present disclosure generally relates to integrated core-shell investment casting molds that provide a filament structure corresponding to a cooling hole pattern in the surface of the turbine blade or stator vane, which provide a leaching pathway for the core portion after metal casting. The invention also relates to core filaments that can be used to supplement the leaching pathway, for example in a core tip portion of the mold.
