An investigation into the corrosion characteristics and mechanism of directionally solidified (DSed) Mg-3Zn-xCa (x = 0, 0.2, 0.5, 0.8 wt.%) alloys in 0.9 wt.% NaCl solution is presented. The DSed microstructure consists of columnar dendrites and eutectics distributed in the interdendritic region. Th...
