Cast irons are thought to be superior in corrosion resistance to plain steels. The differences between cast iron and plain steel are mainly in the existence of graphite and the amount of silicon. The graphite nobility for the matrix results in the electric potential difference between graphite and matrix. Thus the study of the effect of graphite morphology on corrosion resistance in cast irons under mild corrosive environments is needed. In this study, ductile cast irons with different graphite nodule size are austempered, their corrosion potentials are measured and their anodic polarization tests are carried out in 0.01N HCl aq. . The results show that : (1) In ductile cast irons, the smaller is the graphite nodule size, the lower is the corrosion resistance. In ADI, however, the graphite nodule size has a littIe effect on the corrosion resistance. (2) In ADI, the amount of retained austenite and the corrosion resistance decrease as the austempering time increases.
