摘要
Thixomolding is a new process technology for the high-volume production of magnesium products. This paper describes the corrosion properties of thixomolded Mg-Al alloy specimens in the saline environment. The thixomolded specimen exhibits a higher corrosion resistance compared to die cast ones. The anodic polarization curve in 5wt% NaCl solution shows a unique passivation-depassivation behavior. The improved heat transfer between the Mg slurry and the die during the injection process produces a fine microstructure and the enrichment of Al content near the surface. The effect of the alloying element on the corrosion performance is also investigated.
