Scanning acoustic microscope (SAM) is a useful nondestructive technique for obtaining inside information by observing from the surface which cannot be seen by conventional microscopic techniques. In the present article application of SAM to nondestructive evaluation of typical localized corrosion damages is described and advantages of the technique to conventional microscopic techniques are emphasized. Furthermore discussion is addressed to several problems which should be solved before SAM establishes itself as an indispensable corrosion evaluation technique.
