Abstract

Abstract The effects of solution temperature on the corrosion characteristics of Ca-containing AZX911 and AMX602 Mg alloys were investigated in 0.1 M NaCl solution and compared with those of AZ91 and AM60. AZX911 and AMX602 comprise an α-Mg matrix having an spherical Al 2 Ca phase dispersed therein; the Al 2 Ca on AMX602 was approximately twice the amount that on AZX911. Severe corrosion was occurred on both AZX911 and AMX602 at 40 °C and above. In particular, AMX602 was corroded more rapidly, which means that the Al 2 Ca is not capable of blocking the corrosion at the high temperature due to strong galvanic cathode effect.
