| titleOfInvention | Method for customizing core and shell of integrated ceramic mold of hollow turbine blade |
| abstract | The invention discloses a method for customizing a core and a shell of an integrated ceramic mold of a hollow turbine blade. The method comprises the following steps of: preparing alumina-based ceramic slurry with different prescriptions; simultaneously casting the core and the shell of the hollow turbine blade by using different types of ceramic slurry under a vacuum environment; performing vacuum freeze drying and sintering to obtain the core and the shell of the ceramic mold with different components and different performances. In consideration of difference in stress states between the core and the shell and between different cores during pouring of molten metal, and difference in core stripping difficulty between the different cores, the ceramic mold can meet a requirement for pouring of the molten metal through the core and the shell with different components and different mechanical performances. |
