Fabrication of SiC ceramic architectures using stereolithography combined with precursor infiltration and pyrolysis

High‐temperature flexural strength of SiC ceramics prepared by additive manufacturing

“…SiC ceramics with the characteristics of low density, oxidation resistance, high-temperature resistance, and thermal shock resistance, [1][2][3] have been considered as the ideal materials for high-temperature structure in engine applications instead of superalloys. SiC ceramics with the characteristics of low density, oxidation resistance, high-temperature resistance, and thermal shock resistance, [1][2][3] have been considered as the ideal materials for high-temperature structure in engine applications instead of superalloys.…”

“…The development of the hot-end materials in aero-engines with excellent comprehensive performance, especially stable high-temperature mechanical properties, is a key technology that needs immediate attention. SiC ceramics with the characteristics of low density, oxidation resistance, high-temperature resistance, and thermal shock resistance, [1][2][3] have been considered as the ideal materials for high-temperature structure in engine applications instead of superalloys. At present, SiC ceramics have broad applications in high-temperature areas, eg, the high-temperature heat exchanger for metallurgical industrial furnaces with operating temperatures up to 1300°C, and the radiant tubes are used at 1500°C.…”

Fabrication of (SiC-AlN)/ZrB2 Composite with Nano-Micron Hybrid Microstructure via PCS-Derived Ceramics Route

“…The other is to use densification processes, such as polymer impregnation pyrolysis (PIP) and chemical vapor infiltration (CVI). He et al [ 30 ] used PCS as the ceramic precursor to increase the flexural strength of SiC prepared by stereolithography from 15 MPa to 205 MPa using the PIP process. Xiong et al [ 31 ] used the CVI process to increase the tensile strength of the 3D printed PCS-derived SiC lattice from 3.3 MPa to 47.3 MPa.…”

Processing and properties of SiC composites made via binder jet 3D printing and infiltration and pyrolysis of preceramic polymer

“…Stereolithography is based on selectively curing 2D layers of monomer resins loaded with powder particles. One drawback of this approach when used to manufacture silicon carbide objects is that preforms tend to have low density due to low solid loading because of the opacity of SiC powders to light 14,15 . Robocasting utilizes solvent, gel, or paste slurries that are extruded through a nozzle to obtain green objects.…”
