【摘要】 介绍了NiCr/NiSi薄膜热电偶制作方法与过程。与多弧离子镀法相比,采用磁控溅射法镀制的热电偶薄膜成分与靶材接近,膜层致密均匀、平整光滑,临界厚度薄。对研制的NiCr/NiSi薄膜热电偶进行了静态标定与动态标定,薄膜热电偶的灵敏度为40.1μV/℃,线性误差不大于0.75%,时间常数小于0.35 ms.最后将薄膜热电偶温度传感器用于化爆材料模拟切削试验。更多还原

【Abstract】 The fabrication method and process of NiCr-NiSi thin-film thermocouples(TFT) are introduced reasonedly.Compared with Multiple Arc Ion plating, the thin-film of thermocouple which are developed by the Magnetron Sputting are more compactive and smooth,and the contributions are close to the target.The static and dynamic calibration of TFT are proposed,and it is concluded that the Sensitivity are 40.1 μV/℃,linear error is no greater than 0.75% ,and the constant time is less than 0.35ms.At last,TFT are applied to the chemical explosive material simulation cutting test.更多还原
