- 摘要:
- 镍基铸造高温合金因其优异的综合性能成为航空发动机涡轮叶片的主流选择。在熔模铸造过程中,合金熔体在高温下易与陶瓷型壳/型芯发生界面反应,劣化叶片铸件表面质量,甚至导致叶片报废。本文综述了熔模铸造过程镍基高温合金与典型陶瓷型壳/型芯的界面反应研究进展,尤其对不同陶瓷应用过程的优点和不足进行了分析和汇总。在此基础上,提出了匹配熔模铸造技术发展的陶瓷型壳/型芯的研发方向,旨在为镍基高温合金熔体与陶瓷界面反应程度的降低和叶片铸件表面质量的提升提供参考和借鉴。
Owing to excellent comprehensive properties, Nickel-based casting superalloys have become the priority selection for turbine blade in aero engines. During the investment casting process, the interface reaction between alloy and ceramic shell/core is easy to occur, which seriously affects the surface quality and even lead to blades into waster. This paper summarized the current research regarding the interface reaction between nickel-based superalloy and typical ceramic shell/core during investment casting, in which emphasis was given to the advantages and disadvantages of different ceramic in application processes. Based on this, the research and development direction of the ceramic shell/core that match with the investment casting technology was put forward, in order to provide reference for the reduction of the interface reaction degree between Ni-based superalloy melt and ceramic and the improvement of surface quality of blade castings.
