A thermal wave interference model is developed to analyse the response of coatings to pulsed and stepped heating. The influence of the relative thermal properties of coating   and substrate and the possibility of coating translucency are included in the analysis.  The potential of transient techniques for the measurement of coating thickness is   demonstrated and compared with the continuous wave technique. Experimental   results obtained from plasma sprayed zirconia coatings are presented and compared  with theoretical predictions.
