Abstract:

Ni-W alloy coating was electroplated on the surface of mild steel and the effect of current density on its corrosion behavior was evaluated in this paper. The microstructure of the coatings were scanning electron microscopy (SEM) Polarization techniques have been used to investigate the corrosion behavior in 3.5wt.% NaCl. The results showed that the surface morphology of the coatings is strongly influenced by the deposition current density. And the increased of current densities is benefit for the Ni-W coating from0.5 to 4A/dm2, and the critical value of current densities is 4A/dm2, the corrosion resistance of electroplated coating present better worse when current densities exceeds the critical value or more.
