Medical TC4 titanium alloy with surface texture filled with lubricating medium and preparation method of medical TC4 titanium alloy

The invention provides a medical TC4 titanium alloy with a surface texture filled with a lubricating medium and a preparation method of the medical TC4 titanium alloy. According to the method, the surface texture with a certain depth is prepared by using nanosecond laser under proper power and frequency and serves as a positive electrode of an electrode, the electrified lubricating medium in a solution is filled in the texture in an electrophoresis mode, and the surface texture with the certain depth is obtained. And the antifriction and antiwear properties of the medical TC4 titanium alloy can be improved. The nanosecond laser is used for directly machining the surface texture on the medical metal surface, the cost is low, machining is rapid, and pollution is avoided; according to the method, the lubricating medium is directionally enriched in an electrophoresis mode, the operation is simple, the feasibility is high, the enrichment efficiency is high, and the controllability is high; the lubricating medium p
