The Influence of Copper Content on the Elastic Modulus and Antibacterial Properties of Ti-13Nb-13Zr-xCu Alloy

Device-related infection or inflammatory and stress shield are still the main problems faced by titanium alloy implants for long-term implantation application; therefore, it is of great significance to design an with low elastic modulus good antibacterial properties as well biocompatibility. In this paper, Ti-13Nb-13Zr-xCu(x = 3, 7 wt.%) alloys were designed prepared reveal influence Cu content on property. X-ray diffractometer, metallographic microscope, scanning electron transmission microscope used study phase transformation, microstructure, mechanical properties, cytotoxicity alloys. The experimental results have demonstrated that performance significantly improved but corrosion resistance deteriorated increase copper content. Ti-13Nb-13Zr-3Cu a 73 GPa rate over 90% against Staphylococcus aureus (S. aureus) exhibited potential candidate implant in future.
