Abstract

High-ductility ductile iron was alloyed with 0-1.8wt% Ni in this paper. The low-temperature impact toughness test and corrosion test of simulated seawater static whole-soaking were conducted to research the effect of nickel on the low-temperature impact toughness and corrosion resistance of high-ductility ductile iron. The results show that with nickel increasing, the impact toughness under low temperature ascents a great deal, and reaches the highest point with 0.71wt% nickel addition, then descents; while the corrosion resistance has always been growing with the increasing of nickel content. Ductile iron containing 0.71wt% nickel shows the best low-temperature impact toughness (the impact toughness values A_kv of the samples reached 16.6J at -20°C, 12.8J at -40°C respectively) and exhibits the optimum combination properties. The presence of rust layer, which was made up of Fe₃O₄, played certain barrier for electrochemical reaction.
