Abstract

The corrosion resistance of Ni-resist ductile iron was improved after laser surface alloying with pure copper. The corrosion current of laser-surface-alloyed samples is about one order of magnitude lower than the untreated sample. The principal reason for the enhanced corrosion resistance of the laser-surface-alloyed samples is believed due to formation of a Cu2O oxide passive film on the alloyed surface in the chloride solution, although the refinement of the eutectic phase and elimination of the graphite spheres can also contribute to improve their corrosion resistance.
