Abstract
A high-potential Mg alloy used as consumable anode for the underground oil or gas pipeline, storage tank and water pipe is prepared through micro-alloying the Mg-Mn alloy by Mg-Ca and Mg-RE intermediate alloys, and refining by use of special refining agent to obtain Mg MnRECa alloy, which contains proportionally Mn, Ce, Ca, Si, Cu, Ni, Fe and Mg. Its advantages are high open-circuit potential 1.7-1.8 (-V) and high current efficiency (55-60%).
