摘　　要：在GH5188高温合金异形件表面制备了铂铱薄膜热电偶,并将薄膜热电偶放置于焰流台,测试高温合金异形件表面的瞬态温度。经过高温高速焰流灼烧四个循环,总测试时长达到8700 s后,铂铱薄膜热电偶仍可以稳定获取温度数据。这次实验的成功,说明铂铱薄膜热电偶向工程化应用迈出了重要一步。项目团队瞄准薄膜热电偶工程化应用,研究了薄膜制备技术、界面调控、集成制备及信号与系统等内容,突破了13项关键技术,实现了铂铱薄膜热电偶的工程应用。该项实验的突破使得国内在叶片模拟服役条件下具备测温能力。Pt/Ir thin film thermocouples were prepared on the surface of the GH5188 special-shaped high temperature superalloy,and the thin film thermocouples were placed on the flame flow table to test the transient temperature of the surface of the special-shaped high temperature superalloy.After four cycles of high temperature and high-speed flame burning,the total test time reached 8700 s,the Pt/Ir thin film thermocouple can still obtain stable temperature data.The success of this test indicated that Pt/Ir thin film thermocouples have taken an important step towards engineering application.Aiming at the engineering application of thin film thermocouples,the project team investigated the thin film preparation technology,interface control,integrated preparation,signal and system,etc.,broke through 13 key technologies,and realized the engineering application of Pt/Ir thin film thermocouples.The breakthrough of this experiment makes China have the ability of temperature measurement under the condition of blade simulation service.
