Abstract:The influence of chemical composition on corrosion resistance of AZ91D magnesium alloys ingots has been investigated. Mass-loss method was applied to evaluate the corrosion resistance of AZ91D alloys and the data were analyzed by multiple regression. The results show that the corrosion resistance of this alloy can be improved by increasing Al, Zn and Mn in a certain degree, and will drop with increasing Si and heavy metals (Fe, Cu, Ni). It is found that ingots received from company F should be listed into unusable materials in terms of the corrosion resistance, while among the five suppliers, the only local company E supplied excellent AZ91D magnesium alloy ingots with the best corrosion resistance.
Key words: AZ91D magnesium alloy; chemical composition; property of corrosion resistance; corrosion rate
