Embodiment Construction
[0017] The present invention is described in further detail in specific embodiments.
[0018] First place the titanium implant in 1-3M H 2 SO 4 Liquid, the rest of the preparation of pure water. The titanium or titanium alloy of the titanium implant is used as an anode for anodic oxidation, and electrochemical treatment is performed at a voltage of 20-40V, and Pt material is used as a cathode. The anatase-type surface layer oxide film on the surface is relatively rough, and several circular pits of different sizes appear in local areas. The distribution of pores is relatively uniform, and the pore size is small. Observation under a high-power electron microscope shows that the oxide film has a three-dimensional spherical shape. The microstructure of the pores, the distribution of the pores is relatively uniform, the pore size is very small, and the pore size distribution is between 100-200nm. The porous structure is conducive to the growth of new bone tissue and the delivery...
