Thin Film Thermocouples

There are three types thin film thermocouples (TFTCs) fabricated on the nickel-based superalloy substrates, including type-K (Ni-10%Cr/Ni-3%Si), type-S (Pt-10%Rh/Pt) and indium tin oxide (ITO) versus platinum (Pt) TFTCs. All of the samples were calibrated and cycled in tube furnace. The Seebeck coefficient of type-K, type-S and ITO/Pt TFTCs is 36.53 μV/°C, 8.89 μV/°C and 81.67 μV/°C, respectively. The life time of type-K and type-S TFTCs is 3 calibrating cycles (about 25 h) and 2 calibrating cycles (about 20 h), respectively. The ITO/Pt TFTCs shows longer life time that is longer than 5 cycles (about 50 h).
