activated batteries. The potentiodynamic polarization, galvanostatic discharge and
electrochemical impedance spectroscopy of Mg–6% Al–1% Sn and Mg–6% Al–5% Sn
(mass fraction) alloys in seawater were studied and compared with the commercial AZ31
and AP65 alloys. The results show that the Mg–6% Al–1% Sn alloy obtains the most
negative discharge potential of average–1.611 V with a electric current density of 100 …
