Abstract
The affect of adding of Zn on the microstructure and corrosion properties was investigated in this work. Vacuum induce melting was used to obtain the Mg-2Ca-xZn (wt.%) (x = 0%, 1%, 2% and 3%) alloys. Erode test was carried out in the Hank’s simulated body fluid for the alloys and the increasing of weight is carefully measured. The microstructure of the alloys was observed with optical microscope and SEM. It is found that and the Mg-2Ca-1Zn alloy is with the best corrosion resistance. Hardness increases as the adding of Zn in the alloys.
