- Abstract
The corrosion behaviors of AZ81 magnesium alloy with minor Gd addition have been researched in this paper. The results show that with the minor addition of 0.5-1% Gd, the microstructure of AZ81 magnesium alloy is obviously refined, and the spotted, high-melting point phase Al-Gd intermetallic compounds is found in AZ81 magnesium alloy. The corrosion behaviors of AZ81 alloy decreases obviously with the increase of Gd addition. When the content of Gd is 1%, AZ81 magnesium alloy exhibits the lowest corrosion rate. The corrosion rates of AZ81+Gd magnesium alloy in 3.5% NaCl solution are always higher than those in 0.5%NaCl solution.
