Recycling of Mg-Al-Ca Based Alloy by Vacuum Distillation
In this study, it examined recycling of a Mg-Al-Ca based alloy by vacuum distillation. The vacuum distillation used a vacuum distillation apparatus and it evacuated a vacuum and heated the Mg-Al-Ca based alloy to less than 1Pa at 600°C. Condenser temperature changed it into 280-420°C and performed it. It melted and cast the magnesium condensate which I collected by the vacuum distillation and investigated corrosion resistance and mechanical properties. The condensation ratio increased so that condenser temperature was low. The quantity of zinc decreased so that condenser temperature was high. The quantity of calcium increased slightly so that condenser temperature was high. Most of the other elements did not mix it. The corrosion resistance of castings was good. The elongation of castings became bigger than commercial pure magnesium.
