AbstractThe corrosion behaviors of the extruded Mg-0.54Ca, and Mg-1.33Li-0.6Ca alloys in simulated body fluids (SBFs) were investigated using weight loss, hydrogen evolution and pH value measurement as well as dynamic electrochemical technique. The microstructure and corrosion morphology of these alloys were discerned by means of OM and SEM, and their corrosion products were analyzed by XRD. The results show that the microstructure is composed of alpha-Mg matrix and secondary phases: Mg2Ca and CaLi2 for the Mg-1.33Li-0.6Ca alloy, while alpha-Mg and Mg2Ca for the Mg-0.54Ca alloy. At the initial immersion stage, the corrosion rate of the Mg-1.33Li-0.6Ca alloy is slightly faster than that of the Mg-0.54Ca alloy, whereas at the subsequent period the Mg-1.33Li-0.6Ca alloy has a. corrosion resistance higher than the Mg-0.54Ca alloy. Lithium let to the formation of a dense corrosion product layer, which consists LiH, Mg(OH)(2), MgCO3, CaCO3, CaMgCO3 and CaMgPO4 for the Mg-1.33Li-0.6Ca alloy, however, it consists of MgCO3, CaCO3 and CaMgPO4 for Mg-0.54Ca. Pitting and filiform corrosions are the main corrosion types of these alloys in SBFs.
