Abstract

The bonding quality of the coatings can be effectively characterized by ultrasonic nondestructive testing. This paper investigated the ultrasonic wave propagation at the coating interfaces and found that the reflected signals show clear comb filtering effect. Moreover, theory studies proved that the amplitude and phase of the reflected ultrasonic waves will change with the interfacial stiffness. Therefore, a spectral index based on the comb filtering effect was proposed to evaluate the bonding quality. Experiments of different coating samples were carried out by high-frequency ultrasonic scanning system, along with the destructive cross-cut test. The results show that the reflection coefficient and the spectral index can distinguish between samples of level 0 and level 2 from cross-cut test. In addition, the spectral index based on comb filter effect can significantly improve the contrast of the imaging results. This work will provide theoretical basis and technology support for online and full-coverage nondestructive testing of coatings.
