Common biomedical β titanium alloy

New in recent years Newly Developed β-Type Biomedical Titanium Alloy, such as Ti Nb, Ti-Mo, Ti Zr, and Ti TA alloys, are mainly used in medical implants. (V, Al, Ni, Cr, and other elements harmful to the human body are gradually replaced by non-toxic elements such as Nb, Zr, Ta, Sn, Pt, and Mo with good biocompatibility) some medical low modulus β Type a titanium alloy is shown in the figure below. Compared with β-Type, Ti NB alloys have a lower elastic modulus, which is closer to the elastic modulus of human bone, and do not contain toxic elements Al and V. they are suitable for medical metal materials. At present, many kinds of research have been carried out on them.

Applications

Biomedical titanium alloy has excellent biomedical properties, which makes it widely used as follows:

Future development of biomedical titanium alloys

In recent years, the application of titanium alloys in the biomedical field is developing rapidly, which will also put forward higher requirements for the performance of titanium alloys. Combined with the current research status at home and abroad, it is concluded that the future development direction of biomedical titanium alloys is as follows:

1. New type B titanium alloy is the research hotspot and main direction of biomedical titanium alloy materials in the world.

2. Single crystal biomedical titanium alloy. The single-crystal material grown along a certain direction can obtain an elastic modulus very close to that of human bone. The implant made of this single crystal has better modulus matching.

3. Biomedical porous titanium alloy material, whose elastic modulus can pass through the hole, The change of porosity is adjusted to reduce, but the strength is reduced. Therefore, how to improve its mechanical properties is the research direction.

4. Biomedical titanium alloy with super elasticity and shape memory function.

5. The surface modification of biomedical materials can improve the biocompatibility of implants.
