摘要

Magnesium- Rare Earth (Mg-RE) alloys are emerging as potential active anode materials due to their high electrochemical activity and lightweight nature. However, their widespread application is limited by rapid corrosion and insufficient surface stability. This study investigates the effect of thermal processing on the microstructure, corrosion behavior, and active anodic performance of Mg-1Er-1Nd alloy. A key gap addressed is the analysis of the intermetallic phase formation and surface passivation of Mg-1Er-1Nd alloy subjected to heat treatment. Heat-treated specimens (HT1, HT2) showed significant improvement in corrosion resistance compared to the base material (BM), with HT1 exhibiting the lowest corrosion rate of 1.24 ± 0.07 mm/year versus 18.4 ± 1.16 mm/year for BM. The formation of a greater fraction of oxides on treated surfaces contributed to more stable oxide film formation and reduced localized attack. HT1 also demonstrated improved microhardness (42 ± 3 HV), attributed to phase dispersion and diffusion mechanisms. The controlled thermal processing enhanced the active anodic efficiency and mechanical integrity of the Mg-1Er-1Nd alloy, supporting its suitability for high-performance anode applications in corrosive environments.
