Applications of titanium alloys in the medical field

As a new type of alloy and a carrier material, medical titanium alloy is widely used in limb implants, alternative functional materials, dentistry, medical devices and other related fields. Titanium and titanium alloys have the following characteristics: good corrosion resistance, high specific strength, low elastic modulus, fatigue resistance, and good biocompatibility. Among them, good biocompatibility gives it unique advantages compared with other metals, so it is widely favored in the medical field. However, due to its low wear resistance and process performance, efforts to further improve it are also limited. Ongoing.

Implant restorations. The main advantages of titanium and titanium alloys as implant restorations are:

①High strength, good chemical stability and biocompatibility;

② Non-toxic and will not cause harm to the human body;

③ Low elastic modulus, better matched with human bones;

④ Memory alloy has excellent elasticity and shape recovery function.

In summary, the application of titanium in skull repair is mainly reflected in the use of titanium mesh to repair defective skulls. Applications in human cardiovascular aspects include: preparation of artificial heart valves, blood filters, pacemakers and artificial heart pumps, etc.
