Synthesis, Characterization and Antimicrobial Studies of Ti-40Nb-10Ag Implant Biomaterials

Bacterial infection and stress shielding are important issues in orthopedic implants. In this study, Ag element was selected as an antibacterial agent to develop Ti-40Nb-10Ag alloy by spark plasma sintering (SPS). The microstructure, phase constitution, mechanical properties, microhardness, properties of the sintered alloys with different temperatures were systematically studied X-ray diffraction (XRD), scanning electron microscope (SEM), microhardness tests, compressive tests. mainly composed α-Ti, β-Ti, Ti2Ag intermetallic phases. This study shows that change temperature affects microstructure alloy, which results changes its strength, elastic modulus, properties. At 975 °C, good metallurgical bonding developed on surface led excellent ability rate 95.6%. conclusion, prepared SPS at °C is ideal effective for implant.
