With the increasing aging population and the increasing mechanical and sports injuries, the demand of biomedical metal implant materials is increasing. The number of hip revision surgeries has been reported to increase 26% over the last eight years, with an expected increase to 137% in 2030. The biomedical metal implant materials used in clinic at present mainly comprise Co-Cr-Mo alloy, 316L stainless steel, ti and Ti alloy, noble metal and the like.
The existing common metal implant materials are corrosive, ni ions and Cr ions in 316L stainless steel and Co-Cr-Mo alloy are gradually separated out in solution, the Ni ions can cause diseases related to skin, and the existence of Co ions can cause carcinogenic risks. In addition, the modulus of both 316L stainless steel and Co-Cr-Mo alloys is significantly higher than the modulus of elasticity of human bone, resulting in insufficient stress transfer to the bone, resulting in bone resorption and implant loosening failure after years. Titanium alloys, while highly corrosion resistant and biocompatible, have poor wear resistance and abrasive debris from frictional wear can cause "particulate disease" which adversely affects their useful life.
