摘要：
One of the major causes of magnesium corrosion is the presence of iron as an impurity in commercial alloys. Alloying the material with manganese may reduce the corrosion rate acceptable levels. The corrosion rate of a Mg-9% Al-1% Zn alloy containing varying amounts of Mn and Fe correlates with the Fe:Mn ratio in the alloy and in the aluminum-base intermetallics. The ratio is suggested to be the basic parameter determining the corrosion rate for a given thermomechanical history.
