Investigation on 3D printing of silica ceramic cores is crucial to the development of aviation level in China, but the related problems are high-temperature softening and structural anisotropy. Silica ceramic cores were fabricated by DLP light curing 3D printing technology using fused silica powder as a raw material and mullite powder as a modifier. The results show that the ceramic cores have a layer-packed anisotropic structure. The addition of a small amount of mullite powder promotes the sintering densification of ceramic powder and diffusion binding between printing layers. As a result, the structural anisotropy of ceramic cores is relieved, and the flexural strength is enhanced and tended to isotropy. For ceramic cores with 3% mullite powder, the high-temperature flexural strengths in horizontal and vertical printing are up to 18.5 MPa and 16.3 MPa, respectively, which can satisfy the demands for hollow blade casting.

氧化硅陶瓷型芯的3D打印研究对于中国航空水平的发展具有重大意义,其高温软化和结构各向异性是该领域面临的难题。以熔融石英粉为原料、莫来石粉为改性剂,利用DLP光固化3D打印技术制备了氧化硅陶瓷型芯,型芯表现出层状堆积的各向异性结构,少量的莫来石粉体促进了陶瓷颗粒的烧结致密及打印层之间的扩散结合,型芯的各向异性得到缓解,弯曲强度提高并趋于各向同性。当莫来石含量为3%时,其横向、竖向打印高温强度分别达到了18.5 MPa和16.3 MPa,能够很好的满足涡轮叶片的浇铸需求。

氧化硅陶瓷型芯的3D打印研究对于中国航空水平的发展具有重大意义,其高温软化和结构各向异性是该领域面临的难题。以熔融石英粉为原料、莫来石粉为改性剂,利用DLP光固化3D打印技术制备了氧化硅陶瓷型芯,型芯表现出层状堆积的各向异性结构,少量的莫来石粉体促进了陶瓷颗粒的烧结致密及打印层之间的扩散结合,型芯的各向异性得到缓解,弯曲强度提高并趋于各向同性。当莫来石含量为3%时,其横向、竖向打印高温强度分别达到了18.5 MPa和16.3 MPa,能够很好的满足涡轮叶片的浇铸需求。

Investigation on 3D printing of silica ceramic cores is crucial to the development of aviation level in China, but the related problems are high-temperature softening and structural anisotropy. Silica ceramic cores were fabricated by DLP light curing 3D printing technology using fused silica powder as a raw material and mullite powder as a modifier. The results show that the ceramic cores have a layer-packed anisotropic structure. The addition of a small amount of mullite powder promotes the sintering densification of ceramic powder and diffusion binding between printing layers. As a result, the structural anisotropy of ceramic cores is relieved, and the flexural strength is enhanced and tended to isotropy. For ceramic cores with 3% mullite powder, the high-temperature flexural strengths in horizontal and vertical printing are up to 18.5 MPa and 16.3 MPa, respectively, which can satisfy the demands for hollow blade casting.
