  • Titanium implant with surface coating in crater-like porous shape and preparation method thereof, and implant material
    Patent number: 12758681
    Abstract: The present disclosure provides a preparation method of a titanium implant with a surface coating in a crater-like porous shape. A titanium substrate is subjected to polishing, cleaning, and first drying in sequence to obtain a pretreated titanium substrate. This step eliminates an influence of roughness and surface impurities of the titanium substrate on roughness and a structure of a coating formed on a surface of the titanium substrate after micro-arc oxidation, so as to obtain a titanium implant with a specific structure and a desirable biological performance. The micro-arc oxidation is conducted using the pretreated titanium substrate as an anode and iron as a cathode in an electrolyte containing sodium phosphate. In this step, a micro-arc oxidation coating is formed on the surface of the titanium substrate to obtain the titanium implant with a surface coating in a crater-like porous shape.
