Photocuring 3D printing yttrium oxide ceramic core and preparation method thereof
The invention provides a preparation method of a photocuring 3D printing yttrium oxide ceramic core. The method comprises the following steps: ball-milling and mixing surface modified yttrium oxide powder and light-cured resin to prepare yttrium oxide ceramic core slurry, slicing a ceramic core three-dimensional model, setting a printing path, performing 3D printing on the yttrium oxide ceramic core slurry by adopting a photocuring 3D printer to obtain a ceramic core biscuit, and curing and sintering to obtain a yttrium oxide ceramic core. According to the invention, zirconia is coated on the surface of electro-fused yttrium oxide by a solution method, so that the yttrium oxide slurry with relatively good flowing property and controllable viscosity can be obtained; an yttrium oxide ceramic core biscuit with a complex structure is obtained through a photocuring 3D printing process; and the yttrium oxide ceramic core biscuit is sintered at high temperature, so that the zirconium oxide coated on the surface of the yttrium oxide powder and yttrium oxide are subjected to lattice solid solution, and the high-temperature strength of the yttrium oxide ceramic core is further improved.
一种光固化3D打印氧化钇陶瓷型芯的制备方法，通过将表面改性氧化钇粉和光固化树脂球磨混合后制成氧化钇陶瓷型芯料浆，通过对陶瓷型芯三维模型切片处理和设置打印路径，采用光固化3D打印机将氧化钇陶瓷型芯料浆进行3D打印获得陶瓷型芯素坯，再经固化烧结得到氧化钇陶瓷型芯；本发明通过溶液法在电熔氧化钇表面包覆了氧化锆，有利于获得流动性能较好且粘度可控的氧化钇料浆；通过光固化3D打印工艺获得结构复杂的氧化钇陶瓷型芯素坯；通过对氧化钇陶瓷型芯素坯的高温烧结，使得氧化钇粉表面包覆的氧化锆与氧化钇发生晶格固溶，从而进一步提高氧化钇陶瓷型芯的高温强度。
