Abstract Pulse electrodeposition was used to produce the zinc coatings with different grain sizes by changing the peak current density and the additives. The corrosion behaviors of zinc coatings in 3.5% NaCl solution were investigated by potentiodynamic polarization and EIS techniques. The results demonstrated clearly the better corrosion resistance of nanocrystalline zinc coatings compared with conventional coarse-grain zinc coatings. The structure and the crystal orientation had also a significant influence on the corrosion resistance of zinc coatings.
