Preparation method of calcium oxide ceramic core
The invention discloses a calcium oxide ceramic core preparation method, which comprises: carrying out primary coating on calcium oxide powder to obtain primary calcium oxide powder; preparing calcium oxide light-cured ceramic slurry; preparing a calcium oxide ceramic matrix blank through the photocuring ceramic slurry; pre-sintering the calcium oxide ceramic matrix green body to obtain a calcium oxide ceramic matrix; preparing a dipping solution, and dipping the calcium oxide ceramic matrix through the dipping solution; and drying and sintering the dipped calcium oxide ceramic matrix to obtain the calcium oxide ceramic core. The problem that the ceramic core reacts with molten titanium alloy in the high-temperature casting process is solved, and meanwhile, the ceramic core is easily separated from a titanium alloy casting without causing casting damage.
本发明公开一种氧化钙陶瓷型芯制备方法，包括以下步骤：将氧化钙粉体进行一次包覆，得到初级氧化钙粉体；配制氧化钙光固化陶瓷料浆；通过光固化陶瓷料浆制备氧化钙陶瓷基体坯体；将氧化钙陶瓷基体坯体进行预烧结，得到氧化钙陶瓷基体；配制浸渍溶液，通过浸渍溶液对氧化钙陶瓷基体浸渍；对浸渍后的氧化钙陶瓷基体进行干燥、烧结得到所述氧化钙陶瓷型芯。解决了陶瓷型芯在高温浇铸过程中与熔融钛合金反应的问题，同时实现陶瓷型芯容易与钛合金铸件脱离不造成铸件损伤。
