The invention relates to the field of medical materials, and discloses an electrolyte for micro-arc oxidation, application of the electrolyte, an orthopedic implant material and a preparation method of the orthopedic implant material. The electrolyte comprises phosphate, strong base and water. A coating prepared on the surface of zinc alloy through the micro-arc oxidation electrolyte is a zinc oxide coating with high porosity and a three-dimensional structure, the corrosion rate of a zinc-based material is remarkably improved, adhesion and proliferation of osteoblasts can be improved, and application of the medical zinc-based material to preparation of orthopedic implants is promoted. 本发明涉及医用材料领域，公开了一种用于微弧氧化的电解液及其应用和骨科植入材料及其制备方法。本发明所述电解液包括磷酸盐、强碱和水。本发明的微弧氧化电解液在锌合金表面制备的涂层具有高孔隙率和立体结构的氧化锌涂层，不仅显著改善了锌基材料的腐蚀速率，而且能够提高成骨细胞的粘附和增殖，促进医用锌基材料在制备骨科植入物的应用。
