- 摘要:
- 陶瓷型芯广泛应用于飞机发动机涡轮叶片的熔模精密铸造中，以实现涡轮叶片复杂的空心结构。 本文介绍了高温合金熔模精密铸造用陶瓷型芯的应用现状，概述了陶瓷型芯的制备工艺和常用基体材料的研究进展，分别对石英玻璃、电熔刚玉、锆英石、氧化钇等基体材料制备陶瓷型芯的优缺点和研究进展进行了概述。Ceramic cores have been widely used for investment precision casting of turbine blades in aircraft engines and can help fabricate hollow structures in blades. In this paper, the application status of ceramic cores was investigated. Research on the fabrication process and common matrix materials was discussed, and the merits and demerits of ceramic cores fabricated with silica glass, fused alumina, zircon powder, and yttrium oxide were separately discussed.
