Abstract

The invention discloses a Ta2O5 / TiO2 / 3D porous titanium material and a preparation method thereof, and relates to the technical field of preparation of composite metal porous materials. The preparation method comprises the following steps that 3D porous titanium is polished, the polished 3D porous titanium is put into a sodium citrate-based solution for anodic oxidation treatment, the 3D porous titanium subjected to anodic oxidation treatment is dipped into a tantalum coating solution, the impregnated 3D porous titanium is dried, and the dried 3D porous titanium is put into a muffle furnace for sintering.

Description

technical field [0001] The invention relates to the technical field of preparation of composite metal porous materials, more specifically to a Ta 2 o 5 / TiO 2 / 3D porous titanium material and preparation method. Background technique [0002] Due to its high specific strength, easy processing and forming, rich raw material resources and good biocompatibility, titanium alloy materials have developed into functional structural materials commonly used in surgical implants. However, the complex internal environment of the human body will cause the corrosion of titanium alloy materials, resulting in the release of toxic elements, which will reduce the biocompatibility accordingly; moreover, the elastic modulus of titanium alloy is quite different from that of human bone tissue, which is prone to stress shielding effect . It is necessary to find new metal implant materials with better corrosion resistance, better biocompatibility, and mechanical properties closer to human bone....
