Abstract:
A method of monitoring a surface temperature of an environmental barrier coating (EBC) of a hot gas component includes directing an excitation beam having a first wavelength at a layer of a temperature indicator formed on the hot gas component. The method also includes measuring a fluorescent radiation emitted by the temperature indicator. The fluorescent radiation has a second wavelength and an intensity. In addition, the method includes determining a surface temperature of the EBC based on the intensity of the second wavelength of the fluorescent radiation.
