An investigation was carried out to determine the effect of the microstructure of nodular cast iron (NCI) on its cavitation corrosion behavior in natural seawater. The cavitation tests were conducted using a cavitation-induced facility at a frequency of 20 kHz on detached specimens. Morphological examinations on cavitated specimens indicated that the surface of NCI became very rough with large size cavity pits. Examination by optical microscopy of cross-sectioned specimens revealed the presence of microcracks in the bottom of cavity pits. Localized material removal on the NCI surface was due to ductile tearing and brittle modes of failure.
