Abstract
The SCC susceptibility of Mg-7Al alloys with different Ca additions in 0.21 mol/L K2CrO4 + 0.6 mol/L NaCl solution and air environments was investigated by means of repassivation testing,slow strain rate method and SEM.The results indicated that the Ca addition could decrease SCC susceptibility of Mg-7Al alloys and enhance the repassivation ability of the Mg-7Al-0.3 Mn alloy.
