摘要
硅基陶瓷型芯广泛用于1 550℃以下的Ni、Co基高温合金的精密铸造。综述了硅基陶瓷型芯的研究现状。重点介绍了影响硅基陶瓷型芯的主要因素:方石英含量、矿化剂、粉料粒度、烧成温度,并对脱芯工艺进行了阐述。
Silica-base ceramic core is widely used in the investment casting of Ni- and Co-base superalloys below 1 550 ℃. The research status of silica-base ceramic core was reviewed in this paper. Key factors influencing the properties of the ceramic core, such as cristobalite content, mineralizer, granularity and sintering temperature, were presented. Coreremoval process was also introduced.
