“…The same profile was already described by Cai et al 22 in a similar investigation of the electrochemical behavior of three cast titanium alloys with different surface conditions. Niemeyer et al 23 investigated Ti-13Nb-13Zr alloys with interstitial oxygen and also found a similar behavior. The simple exposure of the alloy to air may result in the formation of titanium oxide, considering that titanium presents great affinity to oxygen.…”

Titanium and its alloys have been used in biomedical applications because of their satisfactory mechanical properties, biocompatibility and corrosion resistance. Their high corrosion resistance has been attributed to the formation of a thermodynamically stable titanium oxide layer on the surface of these materials. In the present work, the corrosion behavior of Ti-9Mo (wt %) alloy, doped with oxygen, was evaluated in a phosphate buffered saline (PBS) solution. The results showed a small decrease in the corrosion potential and a reduction in the corrosion rate with the oxygen doping, indicating a higher corrosion resistance is desirable for biomedical applications.

“…Titanium based alloys with different compositions such as Ti-7.5Mo 3,4 , Ti-10Mo 5,6 , Ti-15Mo 7 , Ti-29Nb-13Ta-4.6Zr 8 and Ti-13Nb-13Zr 9 have been studied for biomedical applications. Lin et al 8,9 developed a binary alloy, Ti-7.5Mo, with a low elastic modulus and a high strength/modulus ratio. A significant difference in elastic modulus between implants and bone tissue can lead to stress, and thereby may cause poor osseointegration, while an implant with a low elastic modulus can facilitate bone growth 10 .Over the past decade, various techniques such as sol-gel method 11 , hydrothermal method 12 , photo oxidation reaction 13 , electro spinning method 14 and anodization 15,16 of titanium surface modification have been employed to fabricate implant surfaces.…”

In this study, the effects of the parameters such as applied potential difference, time and annealing temperature in the titania nanotubes formation were evaluated. The morphology of the nanotubes was evaluted by using Field Emission Gun -Scanning Electron Microscope (FEG-SEM), Atomic Force Microscope (AFM), contact angle and X-rays diffraction (XRD). Self-organized nano-structures were formed on the Ti-7.5Mo alloy surface from the same electrolyte (glycerol/NH4F) for all conditions. It was observed that the potential influenced the diameter while the length was changed according to the anodization time lenght. The presence of the phases anatase and rutile was altered by annealing temperature. Results showed that 20V-48h-450 ºC was the better than other conditions for application as biomaterial.

“…Recently, b-type titanium alloys have attracted significant attention, because their alloying b-stabilizing elements, such as Nb, Zr, Ta, and Mo, are biocompatible and nontoxic. [1,4,14] In addition, compared to a and a+b alloys, they exhibit lower Young's modulus, which is closer to that of bone and has better corrosion resistance. [15,16] The Ti-13Nb-13Zr (TNZ) ternary alloy is one of the most promising near b-type titanium alloys for biomedical applications, developed by Davidson and Kovacs in the 1990s.…”

A biomedical b-type Ti-13Nb-13Zr (TNZ) (wt pct) ternary alloy was subjected to severe plastic deformation by means of hydrostatic extrusion (HE) at room temperature without intermediate annealing. Its effect on microstructure, mechanical properties, phase transformations, and texture was investigated by light and electron microscopy, mechanical tests (Vickers microhardness and tensile tests), and XRD analysis. Microstructural investigations by light microscope and transmission electron microscope showed that, after HE, significant grain refinement took place, also reaching high dislocation densities. Increases in strength up to 50 pct occurred, although the elongation to fracture left after HE was almost 9 pct. Furthermore, Young's modulus of HE-processed samples showed slightly lower values than the initial state due to texture. Such mechanical properties combined with lower Young's modulus are favorable for medical applications. Phase transformation analyses demonstrated that both initial and extruded samples consist of a¢ and b phases but that the phase fraction of a¢ was slightly higher after two stages of HE.
