Abstract Satisfactory corrosion resistance remains an issue in the widespread implementation of magnesium (Mg). The use of alloying to improve mechanical properties of Mg generally accelerates corrosion due to microstructural heterogeneity. However, recent works have revealed that additions of elements serving as ‘cathodic poisons’ such as arsenic (As) and germanium (Ge) can reduce cathodic reaction rates and suppress cathodic activation - imparting corrosion resistance. The effect of Ge was translated into a ternary (and mechanically relevant) Mg-alloy system for the first time, revealing an alloy system with a balance of properties, and low rate of corrosion relative to Mg-alloys to date.

通过添加少量锌和锗同时提高镁的耐腐蚀性和强度

摘要 在镁（Mg）的广泛应用中，令人满意的耐腐蚀性仍然是一个问题。由于显微结构的异质性，使用合金化来改善镁的机械性能通常会加速腐蚀。然而，最近的研究表明，添加砷 (As) 和锗 (Ge) 等作为“阴极毒物”的元素可以降低阴极反应速率并抑制阴极活化 - 赋予耐腐蚀性。Ge 的作用首次被转化为三元（和机械相关）镁合金系统，揭示了一种合金系统具有平衡的性能，并且相对于迄今为止的镁合金腐蚀率较低。
