From: A high-efficiency Mg-1Bi-0.5Nd anode magnesium alloy for discharge applications

Scanning electron microscopy (SEM) images showing the surface morphology of the homogenized alloy anodes after 10 h of discharge at 2.5 mA cm−2 and subsequent removal of the discharge products: (a,b) Mg-1Bi-0.5Gd, (c,d) Mg-1Bi-0.5Y, (e,f) Mg-1Bi-0.5Nd, (g,h) Mg-1Bi-0.5Ce, (i,j) Mg-1Bi-0.5La. Images in the left and right columns are at different magnifications to show overall and localized corrosion features, respectively.
