Paper Title:
Corrosion Behavior of Magnesium Alloy AX53 in Simulated Body Fluids
  Abstract

Magnesium alloys have attracted scientists’ attention as potential implant materials, due to their excellent biocompatibility and good mechanical compatibility. Potentiodynamic electrochemical technique was applied to investigate the corrosion behavior of magnesium alloy AX53 (Mg-4.76Al-3.17Ca) in Hank's solutions, 0.9 wt% NaCl+0.7 g/L NaHCO3 solutions and 0.9 wt% NaCl solutions at room temperature. Corrosion morphologies of the alloys were observed by means of scanning electron microscope, and the chemical compositions were examined through x-ray diffraction. The results demonstrated that free corrosion potential (Ecorr) of AX53 in 0.9 wt % NaCl solution rose rapidly at initial stage, and then stabilized, whereas Ecorr of this alloy increased continuously in the other two solutions. Corrosion rates in Hank’s solutions were lower than in the other solutions. Intergranular corrosion occurred in these solutions.
