Effect of Hot Rolling Reduction on the Corrosion Resistance of Mg-Li Alloys

Abstract

Mg-Li alloy samples were subjected to hot rolling with different reduction, and the corrosion resistance of the samples was investigated by potentiodynamic polarization measurements and electrochemical impedance spectroscopy measurements in 3.5% NaCl solution. The results show that the corrosion rate of the Mg-Li alloy first decreases and then increases with increasing rolling reduction.
