Infrared thermal wave detection technology has been found to be a new type of wide attention non-destructive testing (NDT) method due to its non-contact, non-destructive, rapidity, wide imaging field and advantages of direct observation. Key technologies and the latest research progress of the infrared thermal wave technology in parts defects are reviewed in this paper. The key technologies include the heat stimulator, infrared thermal image processing, heat transfer analysis and etc. The existing problems of the technology are also pointed out.

For the disadvantages of the traditional NDT methods for coating defects, Thermal Wave Nondestructive Testing (TWNDT) technology was used to detect coating debonding defect on composite Materials matrix. Numerical simulation method was used to simulate the heat transfer process of thermal wave in the coating material with defects. The factors influencing the testing sensitivity were in-depth studied, including the debonding defect size and coating thickness. Simulation results show that: TWNDT technology can quickly and efficiently identify the size of the coating debonding defects, while the thickness of the coating is an important factor influencing the inspection sensitivity for the thermal wave detection.
