Abstract
A method of fabricating an implant with improved surface properties and an implant fabricated using the same are provided. The method includes immersing a substrate that has titanium or titanium alloy in electrolytic solution including at least one of the group consisting of phosphate or fluoride ion and strontium ion, and forming an oxide film layer with a surface structure having a fine roughness of a micro scale by making at least one of phosphate or fluoride ion and strontium ion react to the titanium or the titanium alloy of the substrate on a surface of the immersed substrate using hydrothermal reaction associated with temperature, pressure and time conditions.

A method of fabricating an implant with improved surface properties comprising:
- immersing a substrate including titanium or titanium alloy in electrolytic solution including at least one of the group consisting of phosphate or fluoride ion and strontium ion;
- and
- forming an oxide film layer with a surface structure having a fine roughness of a micro scale by making at least one of phosphate or fluoride ion and strontium ion react to the titanium or the titanium alloy of the substrate on a surface of the immersed substrate using hydrothermal reaction associated with temperature, pressure and time conditions.
An implant with improved surface properties comprising:
- a substrate including titanium or a titanium alloy;
- and
- an oxide film layer with a surface structure having a fine roughness on a micro scale, and including at least one of the group consisting of titanium phosphate, strontium titanium and strontium titanium phosphate on a surface of the substrate.
An implant with improved surface properties comprising:
- a substrate including titanium or a titanium alloy;
- and
- an oxide film layer with a surface structure having a roughness in a micro unit and including at least one of titanium fluoride, strontium titanium and strontium titanium fluoride oxide on a surface of the substrate.
