Abstract:

The corrosion behaviors of zinc and Zn-In alloy in KOH solution containing polyoxythylene ether are studied by the electrochemical techniques. The experimental results showed that the corrosion of Zn-In alloy was obviously inhibited by the addition of poyoxyethylene ether- The anodic adsorption and desorption of the inhibitor were found from the cyclic polarization curves. There are some unique features on the electrochemical impedance spectra of Zn-In in the alkaline solutions containing the inhibitor. All these experimental phenomena were discussed according to some related theories.
