Magnesium alloy has good potential application in bone tissue repair, but it is extremely susceptible to corrosion in the human physiological environment and loses its original mechanical properties, causing the implant material to fail during service. In order to improve its corrosion resistance and ability to rapidly induce apatite in vitro, a one-step hydrothermal method was used to prepare a micro-nano structured hydroxyapatite coating on magnesium alloys. The polarization resistance of the sample reached 138.680 kΩ·cm2, indicating that the sample has excellent electrochemical performance. The degradation performance of the sample was tested in simulated body fluids. During the 30 d immersion time, the pH value of the simulated body fluids were maintained in the range of 7.10-7.60, and the corrosion rate was lower than 0.400 mm/y. And when immersed for 3 d, hydroxyapatite mineralization were formed on the coating surface, indicating that the micro-nano structural coating can quickly induce the formation of Ca-P products and has good mineralization ability.
