| Abstract: | Present disclosure discloses a method of manufacturing an oxide based bi-ceramic film 5 thermocouple (100). The method incudes soaking a substrate (1) in an aluminium nitrate solution and drying the soaked substrate (1). Further, the dried substrate (1) is heat-treated. Furthermore, a first mixture comprising of indium chloride, tin chloride and isopropyl alcohol is formed and indium chloride is dissolved in the isopropyl alcohol to form a first solution. Additionally, a second mixture is formed comprising indium chloride, aluminium chloride and in isopropyl alcohol, and 10 indium chloride is dissolved in the isopropyl alcohol to form a second solution. Furthermore, the first solution is sprayed on a surface (1a) of the substrate (1) to form a first film (2) and the second solution is sprayed on the surface (1a) of the substrate (1) to form a second film (3) to form the oxide based bi-ceramic film thermocouple (100). |

| Startup Options: | The proposed thermocoup;e includes little or no electromigration and a high melting point and is chemically stable at elevated temperatures. Further, as the thermocouple is made of ceramics, has high operating temperature, high thermal barrier compatibility with applied thermal barrier coating on the blade surface. |
