Effect of Trace Ca on the Corrosion Resistance of ZA124 Magnesium Alloy
Abstract
The effect of trace Ca addition on corrosion resistance of ZA124 magnesium alloy was studied. The results showed that the effect of adding 0.3% Ca on the refinement of the microstructure of the alloy was obvious, in which the reticular transformation was fine and intermittent or strip-like, and no new phase was formed. With the addition of Ca, the corrosion rate and current density of the alloy in 3.5% NaCl solution decreased, which improved the corrosion resistance of the alloy. When the calcium content was 0.3%, the alloy had the best corrosion resistance.
