Preparation method of alumina-based ceramic core and alumina-based ceramic core
The invention relates to the technical field of ceramic additive manufacturing, and discloses a preparation method of an alumina-based ceramic core and the alumina-based ceramic core, the preparation method comprises the following steps: adding mixed powder of PMMA microspheres and alumina ceramic powder into a photosensitive resin premixed solution, and carrying out ball milling to obtain alumina-based ceramic slurry; adding the alumina-based ceramic slurry into a trough of a 3D printer, and printing under the irradiation of a light source to obtain an alumina-based ceramic core biscuit; and degreasing and sintering the alumina-based ceramic core biscuit to obtain the alumina-based ceramic core. Therefore, according to the preparation method, the process cost can be effectively reduced, the production efficiency can be improved, and meanwhile, the porosity of the aluminum oxide-based ceramic core can be improved, so that the depoling efficiency is improved.
本申请涉及陶瓷增材制造技术领域，公开一种氧化铝基陶瓷型芯的制备方法和氧化铝基陶瓷型芯，制备方法包括以下步骤：将PMMA微球和氧化铝陶瓷粉料的混合粉体加入至光敏树脂预混液中，通过球磨得到氧化铝基陶瓷浆料；将氧化铝基陶瓷浆料加入至3D打印机的料槽内，并在光源照射下进行打印，以得到氧化铝基陶瓷型芯素坯；将氧化铝基陶瓷型芯素坯进行脱脂和烧结，以得到氧化铝基陶瓷型芯。这样，该制备方法能有效降低工艺成本，提高生产效率，同时还能提高氧化铝基陶瓷型芯的孔隙率，从而提高脱芯效率。
