%X Simulated body fluid (SBF) is a common medium for in vitro corrosion analysis. The individual influence and synergy of the SBF components on the corrosion of commercially pure Mg are investigated in this study. The results demonstrate that corrosion acceleration in presence of the synthetic pH buffer, Tris/HCl, is attributed to the combined effect of three factors: increased Cl− concentration, complexation of Mg2+ and Ca2+ and consumption of OH− needed for products formation. In Tris/HCl-free SBF, the synergy between Ca2+, Mg2+, HPO42- and HCO3− assures slowest Mg degradation due to growth of partially protective layer that becomes thicker with time.
