摘要：

In this work, Al-Zn-Mg sacrificial anode was developed from recycled aluminum and zinc. Characterization of the alloy using XRD, TEM and optical microscopy was conducted. Also, the influence of precipitation hardening time on the performance of the sacrificial anodes in seawater was investigated. The results indicated that the formation of both stable and metastable MgZn2 phase during precipitation hardening process has a significant effect on the corrosion behavior of the alloy. The high anodic efficiency of the alloy was attributed to the formation of the stable MgZn2 (eta-phase) within the aluminum matrix.
