The most important properties of metal implants are formability, machinability and polishability. They must maintain functionality during the expected service life and not deteriorate when subjected to fatigue, abrasion, corrosion and impact loads. Titanium and titanium alloys meet all requirements. the above requirements.
The titanium materials specified for surgical transplant materials are mainly pure titanium and Ti-6Al-4VELI alloy. Recently, transplant materials Ti-6Al-7Nb and Ti-13Nb1-13Zr, which have good affinity with the human body, have also been approved by ASTM standards.
Using titanium rods to make artificial bones, cells can regenerate on them and bones can grow. Titanium has good affinity with human bones, epithelium, and founding tissues. In order to improve the surface quality of implant materials connected to human bone, it is also an effective method to apply a bioceramic layer to the roughened surface.
At present, titanium and titanium alloy titanium equipment, titanium coils, titanium heat exchangers, titanium reactors, titanium evaporators have been widely used in artificial bone joints, artificial bones, joint foot plates, broken bone fixators, intramedullary nails, artificial Heart valves, skull, etc.
