Abstract In order to meet the clinical requirements for corrosion resistance and osteogenesis of magnesium-based metal implants, the dense and uniform Mg-Fe-layered double hydroxide (Fe-LDH) coatings were prepared on the AZ91D Mg alloy matrix by hydrothermal method and the Fe-LDH/AZ91D samples were obtained. Electrochemical and hydrogen evolution experiments were performed to explore the effects of coatings on corrosion resistance and its in-vitro performance. Combining CCK-8 and in-vitro mineralization experiments, the biocompatibility and osteogenic properties of Fe-LDH/AZ91D were studied. The results show that the existence of the Fe-LDH coating establishes a barrier between AZ91D and the corrosive liquid and improves the corrosion resistance of the alloy. The corrosion inhibition efficiency of the modified magnesium alloy reaches 92.76%. After immersion in PBS for 14 days, the mass loss rate of AZ91D (40.59%) is almost 1.6 times that of Fe-LDH/AZ91D (25.16%), and the corrosion rate (4.14 mm/a) is about twice that of Fe-LDH/AZ91D (2.13 mm/a). The leaching solutions with different Fe-LDH/AZ91D volume fractions have good cell compatibility and can maintain the osteogenic activity of the cells, reaching the same level as the control group.
