Electrochemical corrosion behavior of as-cast Zn-rich Zn-Mg alloys in a 0.06 M NaCl solution
The electrochemical corrosion behavior of as-cast samples of Zn-1.2 wt.% and Zn-2.0 wt.%
Mg alloys, solidified under similar cooling rates, is investigated in the present study. A
stagnant and naturally aerated 0.06 M NaCl solution at 25 o C was used in the corrosion
tests. In order to evaluate the corrosion resistance, electrochemical impedance spectroscopy
(EIS) plots, potentiodynamic polarization curves and an equivalent circuit are used. It is
found that the increase in the alloy Mg content (from 1.2 wt.% to 2.0 wt.%) refines both the Zn …
