摘要

The microstructures and electrochemical behavior of Mg-Al-Zn-In-Ga alloys are investigated by scanning electron microscopy (SEM), X-ray diffraction (XRD), galvanostatic oxidation, potentiodynamic polarization and electrochemical impedance spectroscopy (EIS). Their performances as anode for Mg-CuCl water-activated battery are also evaluated. It is found that appropriate Ga alloying (1 wt.%) could promote the electrochemical properties of Mg-Al-Zn-In alloy, but over alloying (2 wt.%) may increase the self-corrosion and decrease the discharge capability. The Mg- 6%Al-3%Zn-1%In-1%Ga alloy with desirable corrosion resistance and discharge performance is a kind of promising anode materials for broadening the Mg power sources application.
