摘要:

隨著航空發動機的發展，熱障涂層已經變為未來高性能發動機不可缺少的技術，其隔熱效果的準確評價與預測是進行渦輪葉片優化設計、發動機性能提升的關鍵問題。回顧了近些年來渦輪葉片熱障涂層的隔熱效果研究的理論方法、模擬實驗裝置與測溫技術的研究進展，進一步從材料參數、服役環境以及渦輪葉片結構3個方面介紹了渦輪葉片熱障涂層隔熱效果的影響因素和有關規律發現。最后展望了熱障涂層隔熱效果研究的發展趨勢和挑戰。影響熱障涂層隔熱效果的服役環境和冷卻結構方面因素眾多，當前的實驗研究還不充分，未來熱障涂層隔熱效果的研究趨勢是：優化熱障涂層與氣膜冷卻相互影響及其服役可靠性相互耦合的評價理論和試驗方法，開發針對渦輪葉片服役環境下熱障涂層表面和界面溫度測量技術，研究高速旋轉下燃氣、冷氣等相關參數對隔熱效果和可靠性的影響因素。

Abstract:

With the development of aeroengines, thermal barrier coating (TBC) has become one of the key technologies for future high performance aero-engine turbine blade. Evaluation and prediction of thermal insulation performance are the key problems for TBC optimization design of turbine blade and performance improvement of aero-engine. In this paper, the theory analysis methods, testing devices and temperature measuring techniques for TBC thermal insulation performance in recent years are reviewed, and the effects of material parameters, service environment and structure of turbine blade on TBC thermal insulation performance are introduced. Finally, the research development trend and challenges of TBC thermal insulation performance on turbine blades are prospected. There are many factors affecting the thermal insulation effectiveness of TBC from service environment and structure of turbine blade aspects, and the current experimental research is not sufficient. The development trends of the thermal insulation effectiveness of TBC contain: (i) improving evaluation theory of interaction between TBC and film cooling and testing method for reliability of TBC in service; (ii) developing the technology for measuring the surface and interface temperature of TBC in the service condition; (iii) investigating these influence of parameters about gas and coolant on thermal insulation effectiveness and reliability of TBC under high speed rotation.
