摘要	The morphology, porosity and corrosion resistance of MAO coatings on as-extruded Mg-Ca alloys were analysed using SEM, XRD, EDS and electrochemical tests. The roles of non-through and through-pores in the MAO coating were identified. The results demonstrated that the corrosion resistance of the MAO-coated Mg-Ca alloys is related to the corrosion resistance of the substrates, the porosity of the MAO coating and the galvanic effect. Chemical and electrochemical corrosion alternately occurred on the MAO coatings. The alternating chemical and electrochemical corrosion mechanisms for the MAO coating are discussed.
