Abstract

The formation of a nanostructured TiO2 layer in components based on titanium alloys is an efficient way to increase the chances of success in orthopedic and dental implant surgeries. The main objective of this research project is to evaluate the preparation of TiO2 nanotube layers on samples of Ti-Nb alloys. These alloys form the basis of Ti alloys already commercially used in orthopedic implants, have low elastic modulus, reasonable mechanical strength and are biocompatible. This work will involve preparation of Ti-Nb alloys with different Nb contents using arc-melting under an inert atmosphere. Samples produced will be plastically formed and anodized using HF-based electrolytes. These samples will be characterized using scanning electron microscopy and X-ray diffraction technique. The development of this research will allow us to know the effect of Nb on the formation of nanotubes in Ti alloys.
