Paper Abstract

The thermal inspection technique of time-resolved infrared radiometry (TRIR) has been developed as a nondestructive characterization method for examination of multilayer materials systems. Applications of the technique include detecting defects such as disbonds in protective coatings which could lead to coating failure. This technique is an extension of earlier thermal wave imaging techniques developed for examination of material microstructure and defects. The TRIR technique is totally noncontacting and allows quantitative measurements to be made of both the coating thickness and the integrity of the bond between the coating and the substrate within the same measurements. In the present work we review the basics to the TRIR technique and examine the use of the TRIR technique for inspection of organic coatings.
