Large Theoretical Capacity Magnesium Sacrificial Anode Protection For Oil Platform
Large Theoretical Capacity Magnesium Sacrificial Anode Protection For Oil Platform
Introduction:
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 magnesium surface. Therefore, in the aqueous medium, the microscopic corrosion battery driving force 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 low density, large theoretical capacitance, negative potential, and low polarizability. The driving voltage is very large, and it is suitable for the protection of metal components in soil and fresh water with high resistivity.
