The complex ceramic core used for hollow turbine blades requires high porosity and flexural strength. This work combined vat photopolymerization 3D printing with sacrificial template method to prepare Al2O3 ceramic cores with strip‐shaped pores using polyamide 6 (PA6) fibers as templates. When the porosity was greater than 30%, the maximum flexural strength reached up to 110.48 MPa. The sacrificial templating method improved the porosity of Al2O3 ceramic cores, forming an internal porous structure that combined strip‐shaped large pores with irregularly shaped small pores. The influences of PA6 fiber content and diameter on the shrinkage, porosity, microstructure, and comprehensive properties of alumina ceramic cores were studied, revealing the mechanism of the coexistence of high porosity and high strength.

Wetting behavior and interfacial reactions between a Ni-based superalloy and silica-based ceramic cores containing 10 wt.%, 30 wt.% and 50 wt.% ZrSiO4 were studied using a sessile drop method. The reaction products were characterized by SEM/EDS, EPMA and XPS analysis. SiO2 was the main component in the ceramic cores taking part in the interfacial reactions and the reaction products were composed mainly of Al2O3 layer with some ZrOx scattered. A Cr2O3 halo formed outside the wetted ceramic surface. The wetting angle increased in the initial stage to a peak value and then decreased to a constant value. The increase of the wetting angle may be attributed to the gas evaporation at the interface and the decrease of the wetting angle was due to the formation of the reaction layer at the interface.
