Abstract: A method for treating a surface of a metal implant includes a polishing step, a grafting step and a surface modifying step. The polishing step includes polishing a surface of a metal implant to remove an uneven, natural oxide layer on the surface of the metal implant and to generate an even oxide layer on the surface of the metal implant.

The surface modifying step includes changing a property of the surface of the metal implant with the macromolecular anti-adhesion layer by high temperature and high pressure, providing the metal implant with high hydrophilicity.
