摘要
高温合金空心叶片是航空发动机和燃气轮机的关键部件,而陶瓷型芯是形成叶片空心内腔的过渡部件,其性能直接影响空心叶片的精度和成品率。目前,高温合金叶片内腔冷却流道日益复杂,对陶瓷型芯的性能提出了更高要求,亟需研究综合性能更加优良的陶瓷型芯。概述了国内外矿化剂对陶瓷型芯性能的影响规律,归纳了矿化机理,综述了目前的研究现状,对未来矿化剂增强陶瓷型芯性能的发展方向进行了展望。
Superalloy hollow blade is the key component of aeroengine and gas turbine, and ceramic core is the transition component to form the hollow inner cavity of the blade. Its performance directly affects the accuracy and qualified rate. At present, the structure of the air-cooled channel in the inner cavity of the superalloy hollow blade is becoming more and more complex, which puts forward higher requirements for the performance of the ceramic core. It is urgent to study ceramic core with better comprehensive performance. This paper summarizes the influence law of mineralizers on the properties of ceramic cores at home and abroad,summarizes the mineralization mechanism, and summarizes the current research status. Based on the current research status, the development direction of mineralizer reinforced ceramic core in the future is prospected.
