The choice of metallic materials for use in orthopedic and dental implants is made by evaluating physical, chemical and biocompatibility properties. Among these materials we highlight titanium-based alloys, such as those from the Ti-Al-Nb system, which have high chemical stability and biocompatibility attributed to the presence of niobium. Among these materials we highlight titanium-based alloys, such as those from the Ti-Al-Nb system, which have high chemical stability and biocompatibility attributed to the presence of niobium. Surface characterization was performed using XRF, SEM, XRD and XPS techniques. It was observed a uniform structure and distribution of the α - equiaxial phase involved by the β phase in the grain boundaries, besides the formation of alkaline titanate hydrogel by the chemical attack of the NaOH solution on the surface. The results obtained allowed making some considerations about aluminum and niobium contents, giving the Ti-6Al-7Nb alloy adequate characteristics for use in implantable biomedical devices.
