Magnesium Alloy Anodes High Chemical Activity High Driving Voltage
Magnesium is a sacrificial anode material commonly used in electrochemical cathodic protection engineering. It has high chemical activity, its electrode potential is relatively negative, and its driving voltage is high. At the same time, it is difficult to form an effective protective film on the surface of magnesium. Therefore, in the aqueous medium, the driving force of the microscopic corrosion battery on the magnesium surface is large, the protective film is easy to dissolve, the self-corrosion of magnesium is very strong, and the hydrogen evolution reaction 2H++2e—H2 occurs on the cathode. Magnesium-based sacrificial anodes include pure magnesium, Mg-Mn alloys, and Mg-AI-Zn-Mn alloys. Their common characteristics are small density, large theoretical capacitance, negative potential, and low polarizability. The driving voltage is very large (>0.6V), which is suitable for the protection of metal components in soil with high resistivity and fresh water.
