Understanding Magnesium Sacrificial Anodes: The Basics
1. Pure Magnesium Sacrificial Anodes: Magnesium is a reactive metal, and its electrochemical properties are significantly influenced by impurities and alloying elements. When magnesium contains impurities, especially those with lower hydrogen evolution potential, its tendency for self-dissolution increases, leading to decreased current efficiency. Some impurity elements, like Fe, Co, and Mn, dissolve as single-phase solutes…
