Abstract

Pulse thermography has been proved an effective method for the quality testing of coating materials. Surface temperature variations not only reveal the shape and position of the defect, but also reflect the property of the second layer. In this paper, the relationship between surface temperature and the property of the second layer is obtained by analyzing the one-dimensional theoretical model of transient heat conduction in a double-layer structure under an instantaneous plane source, which establish the theoretical basis of the recognition by infrared time depend characteristic; typical materials painted the same coating are manufactured as the specimens for the recognition study; pulse light stimulation is adopted, and an IR camera is used to record the temperature varies of the surface. Different materials can be distinguished by comparing the log temperature vs. time curves, furthermore the theoretical log T-t curves are also shown as a comparison, and the errors are analyzed.
