Abstract
A system and method for determining the condition of a thermal barrier coating on a base metal component, comprising the use of an induction coil to input into the metallic base layer through the coating layer, a temporally varying heat waveform, and measuring the temperature of the coating surface layer resulting from the input of the heat waveform using a temperature sensor disposed close to the surface of the coating layer. A controller correlates a signal from the temporally varying output of the temperature sensor with a signal corresponding to the temporally varying heat waveform, to determine the phase angle between the signals. The controller uses a mathematical relationship between the phase angle and the frequency of the heat waveform to determine the thermal properties of the non-metallic coating. Both the thermal diffusivity and the barrier coating thickness can be accurately obtained by this method and apparatus.
