【 摘 要 】

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.
