Effects of zinc ion concentration on the surface film structure of mild steel in aqueous solution with chloride ion

Islam, M. S.*; Otani, Kyohei ; Sakairi, Masatoshi*

In the previous study, it was founded that Zn $^{2+}$ significantly inhibited the corrosion of mild steel in Cl $^{-}$ aqueous solution at room temperature. It is still not fully elucidated the corrosion inhibition ability of Zn $^{2+}$ concentration on the steel in Cl $^{-}$ aqueous solutions. In the present study, the effects of Zn $^{2+}$ concentration on the corrosion inhibition of mild steel were investigated by immersion tests. From the immersion tests, it was found that mass change of specimen closely related to the Zn $^{2+}$ concentration in the solutions. SEM images showed that the numbers of pits are decreasing with increasing the Zn $^{2+}$ concentration. XPS and AES results showed that Zn $^{2+}$ existed as hydroxides by forming a layer with the surface film and the coverage of the layer is increased with increase in Zn $^{2+}$ concentration.
