Abstract

The use of a custom Mg-3Pb alloy as a sacrificial anode for protecting AZ31, AM60, and AZ91 Mg alloys in 0.1 M NaCl solution was evaluated using surface characterization, mass loss, electrochemical measurements, and gravimetric H₂ collection. The Mg-3Pb alloy exhibited consistently lower open circuit potential values than the protected alloys and demonstrated protection efficiencies over 95 %. No polarity reversal or cathodic activation was observed, despite increased anomalous H₂ evolution. These findings confirm the effectiveness and viability of Mg-3Pb alloy as a sacrificial anode for the cathodic protection of AZ31, AM60, and AZ91 Mg alloys.

探索 Mg-3Pb 合金作为 AZ31、AM60 和 AZ91 镁合金阴极保护牺牲阳极的可行性

使用定制Mg- 3pb合金作为牺牲阳极在0.1 M NaCl溶液中保护AZ31、AM60和AZ91镁合金，通过表面表征、质量损失、电化学测量和重量H2收集来评估。Mg-3Pb合金的开路电位值始终低于保护合金，保护效率超过95% %。尽管H2的异常演化增加，但未观察到极性逆转或阴极活化。这些结果证实了Mg- 3pb合金作为牺牲阳极对AZ31、AM60和AZ91镁合金阴极保护的有效性和可行性。
