SiC_(f)/SiC复合材料涡轮导向叶片研究进展

Research progress of SiC_(f)/SiC turbine guide vanes:A review

随着航空发动机性能进一步提升,急需发展新型轻质、耐高温、长寿命的陶瓷基复合材料导向叶片,以解决目前高温合金材料使用温度达到极限的问题。本文从导向叶片服役环境特点、材料特点、制造工艺、考核验证方法及无损检测技术等方面系统的综述了目前国内外SiC_(f)/SiC复合材料导向叶片研究进展情况,以期为国内航空发动机领域陶瓷基复合材料导向叶片的相关研究工作提供一定的参考。

With the further improvement of aero-engine performance,it's urgent to develop new lightweight,hightemperature-resistant and long-life ceramic matrix composite guide vanes to solve the problem that the superalloy materials have reached their service temperature limit.This paper systematically reviews the current research progress of SiC_(f)/SiC guide vanes from the service environment characteristics,material characteristics,manufacturing process,assessment method,and nondestructive testing technology,in order to provide a certain reference for the domestic relevant research work of ceramic matrix composite guide blades in the field of aeroengine.
