摘要：Magnesium and its alloys have excellent biocompatibility and mechanical compatibility. The reduction in their rapid corrosion rates becomes the key to clinical applications. The current study on magnesium alloys as biomaterials is focused on the surface modification. The history and recent cutting edge researches on the bio-coatings on medical magnesium alloys were predominately reviewed. The emphasis was placed on the recent progress of the preparation, corrosion resistance and biocompatibility of the bio-coatings. These coatings include hydroxyaptite (HA), micro arc oxidation films or plasma electrolyte oxidation coatings, degradable polymers (polylactic acid (PLA), poly (lactide-co-glycolide) (PLGA) and chitosan), inert bio-ceramic coatings (TiO2, Al2O3and ZrO2) and chemical conversion films (fluoride and rare earth) and ion implanted titanium and zinc films as well. The developmental trends were proposed.
