一种方法包括：采用纯镁或镁合金作为基材，对基材进行打磨和清洗：制备含有0.8-8 mmol/L Zn^2＋，30-50 mmol/L Ca⁺.15-35 mmol的电解液 /L H₂PO₄ 0-0.5 mol/L NaNO₃，0-0.05 mmo/L 镁离子络合剂； 以基板材料为阴极，石墨片为阳极，将电解液加热至60～90℃。 将阴极和阳极同步浸入电解液中；在电解液中进行电化学沉积20-60分钟。

A method including：employing pure magnesium or a magnesium alloy as a substrate material，and sanding and cleaning the substrate material:preparing an clectrolyte including 0.8-8 mmol/L of Zn^2＋，30-50 mmol/L of Ca^＋.15-35 mmol/L of H₂PO₄ 0-0.5 mol/L of NaNO₃，and 0-0.05 mmo/L of a magnesium ion complexing agent; employing the substrate material as a cathode, a graphite flake as an anode, heating the electrolyte to a temperature of between 60 and 90℃. and synchronously immersing the cathode and the anode into the electrolyte；and implementing an electrochemical deposition method in the electrolyte for between 20 and 60 min.
