Abstract: Biomedical Ti alloy implants are required to have excellent mechanical properties such as high strength, certain plastic toughness and low elastic modulus in order to adapt to the complex environment inside the human body. The higher the self corrosion potential and the smaller the corrosion current density are, the better the corrosion resistance of the alloy is. The less metal ions released by the alloy in the medical process is, the less secondary damage to the patient is. The treatment process, mechanical properties and corrosion resistance of the third generation biomedical Ti alloy were reviewed, in order to provide a valuable reference for material researchers in the application research of biological alloys.
