摘要	Microstructure, composition and the corrosion resistance of Mg-Ca alloys were analysed using SEM, EDS, XPS, EPMA, XRD, electrochemical and immersion tests. The results revealed that Ca played a dual role, decreasing the corrosion rate due to the refinement of grain size and accelerating corrosion due to the formation of the Mg2Ca phase. The Mg2Ca particles coexisted with Fe and Si led to pitting corrosion. The Mg-0.79Ca alloy had the highest hardness, ultimate tensile/yielding strength and corrosion resistance in comparison with the Mg-0.54Ca and Mg-1.35Ca alloys, representing the promising candidate for degradable biomaterials.
