The invention relates to a method for preparing a strontium-doped calcium phosphate coating on the surface of magnesium alloy through a one-step hydrothermal method. The method includes the steps that a coating solution is placed in a reaction still, and a magnesium alloy sample treated through alkali is soaked into the coating solution; the reaction still is placed in a drying oven, and heat preservation lasts for 1-3 h at the temperature of 90-110 DEG C; and finally, the reaction still is cooled to an indoor temperature along with the drying oven, and the magnesium alloy sample is taken out, rinsed with deionized water and then dried. The prepared coating on the surface of the magnesium alloy is structurally divided into an upper layer and a lower layer. The upper layer of the coating is of a flower-shaped cluster structure, the lower layer of the coating is of a compact sheet structure, and the coating thickness is 1-2 microns. In an in-vitro immersion experiment, deposited hydroxyapatite appears on the first day to the third day, and good biological activity is achieved; and moreover the alternating-current impedance is 7500-14000 ohm.cm<2>. The biological activity of the magnesium alloy is improved, and meanwhile corrosion resistance of the magnesium alloy in simulated body fluid is improved. The preparation technology is simple, the method is environmentally friendly, and great commercial popularizing value can be achieved.
