HIGH POTENTIAL MAGNESIUM ALLOY SACRIFICIAL ANODE AND MANUFACTURING METHOD THEREOF

摘要

Provided are a high potential Mg alloy sacrificial anode and a manufacturing method thereof, the high potential Mg alloy sacrificial anode has the following chemical composition percent by weight: Zn 0 - 0.4%, Al = 0.01%, Si = 0.02%, Mn = 0.05%, Fe = 0.03%, Ni = 0.003%, Cu = 0.005%, the remainder being Mg, and the open-circuit potential of the high potential Mg alloy sacrificial anode is above -1.80V, the current efficiency is above 60%. The manufacturing method of the high potential Mg alloy sacrificial anode is easy and inexpensive, and the electrical properties of the high potential Mg alloy sacrificial anode are superior to ASTM standard requirements.
