Synergistic Effect of NaCl and SO2 on the Initial Atmospheric Corrosion of Zinc Under Wet–Dry Cyclic Conditions

The synergistic effect of NaCl and SO 2 on the atmospheric corrosion of zinc has been studied at equivalent total but different ratios of molar deposition rate under wet–dry cyclic conditions. The results show that the corrosion rates, corrosion morphologies and the composition of the corrosion prod...

Description
Summary:The synergistic effect of NaCl and SO 2 on the atmospheric corrosion of zinc has been studied at equivalent total but different ratios of molar deposition rate under wet–dry cyclic conditions. The results show that the corrosion rates, corrosion morphologies and the composition of the corrosion products are strongly influenced by the molar deposition rate ratio of NaCl and SO 2 (NaCl/SO 2 ). The corrosivity of NaCl and SO 2 toward zinc increases in order of SO 2
