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.
