摘要：

Scanning acoustic microscopy (SAM) was used as a complementary method to electrochemical impedance spectroscopy to characterize delamination processes at a water borne epoxy coating/steel interface. The nature of the dispersing agent incorporated in the water borne epoxy coating was found to have a strong influence on the coating performance, SAM results supported the impedance data, the same ranking of the specimens being obtained. SAM observations also gave complementary information on the initiation sites of the delamination, on the morphology of the blisters and qualitatively on their growth rate.
