dc.description.abstract | Medical grade of both titanium (Ti) and Ti6Al4V alloy are recognized as the metallic biomaterials with the better
outcomes for clinical repair of bone tissue thanks to their suitable mechanical properties and corrosion resistance.
However, those Ti advantages are not enough to avoid failure risks of bone implants; between 5 and
10% of Ti implants fail due to a deficient osseointegration, within 5 years of post-implantation. Most of these
failures indicate the necessity of getting a better biomechanical-biofunctional balance. Microstructural and tribomechanical
characterizations were performed on Ti6Al4V samples obtained by selective laser melting and
subjected to different surface treatments (thermal stress relief, acid etching, chemical treatment and thermochemical
treatment). Scanning electron microscopy and X-ray diffraction were used for detailed characterization
of the elemental composition, phase analysis and surface morphology. Micro-hardness and scratch tests were
employed to evaluate the tribo-mechanical properties, which were improved after consecutive surface treatments.
Protuberances with spherical morphology, as a remainder of the original powder, were present on the
surface. The resulting modified surfaces were constituted by rutile (major phase) and anatase (minor phase).
Submicro-nano-topographies were obtained after the chemical and thermochemical treatments. | es |
