The invention discloses bone-like bioactive coating medical material which is prepared by adopting an electrochemical method. The invention adopts an electrolytic deposition method and imitates the forming process of a natural bone. Electrolyte solution contains calcium, a phosphorous compound and bone matrix collagen, a medical metal transplant body is taken as a working electrode, platinum is taken as a reference electrode, the electrode reaction causes partial pH value of the electrolyte solution around the medical metal transplant body to ascend, thereby leading collagen to be gelatinized, in cooperation with the deposition of calcium phosphate mineral, the bone-like bioactive coating is formed on the medical metal surface. Through the adoption of the invention method, the bioactive coating acquired on the surface of the metal transplant body is similar to the natural bone in the component and the structure, and has favorable biological activity, thus the disadvantages that the biological activity of the business use hydroxyapatite coating is limited, the required curing time is long, etc. are solved. The preparation process of the invention is simple, highly effective and easy to be industrialized.
