“…Among many metallic biomaterials, Ti-based alloys containing no toxic elements or a small amount of toxic elements have been developed as implant materials because of their high biocompatibility, superior mechanical properties, and high corrosion resistance. [30][31][32][33][34][35][36] The Ti-Zr based alloy system is known to use Ti-based alloys for dental casting. 30,37) More recently, Ti-Zr and Ti-Zr-based alloys have been developed for use as new highly biocompatible Ti-based biomaterials.…”

Ti-Zr binary metallic wires without toxic elements were developed by an arc-melt-type melt-extraction method for potential application as biomedical materials. The Ti-Zr binary alloy showed high wire forming capability during the melt-extraction process, independent of the Ti concentration. Therefore, it was possible to form rapidly quenched wires using Ti 100Àx Zr x (x ¼ 10 at% to 80 at%) alloys. Continuous binary TiZr alloy wires had good white luster, negligible surface roughness, high tensile strength, and high bending ductility.

In this paper the inuence of alcohols as the process control agents on β-Ti alloys preparation using mechanical alloying process was investigated. Three types of alcohols: methanol, ethanol and isopropanol were used in mechanical alloying of . Pure Ti, Ta, Nb powders and process control agents were alloyed under argon atmosphere in shaker type mill (Spex 8000). Using X-ray diraction technique, there has been observed the β phase formation after 3 h of mechanical alloying process. Using alcohols as process control agent it is possible to obtain nanocrystalline powders of titanium alloys. The milled powder was sintered in vacuum using hot pressing with high frequency induction heating. It has been shown that sintering process of powders prepared with alcohols as process control agents results in oxides and carbides formation in the alloy structure. Moreover some part of alcohol could evaporate leaving open spaces which results in relatively high porosity of the sinters.

The use of titania (TiO 2 ) nanotubes is becoming one of the most attractive techniques as surface treatment for implants due its combination of morphology (that accelerates osteoblast adhesion and proliferation), bioactivity and possibility of being use as a drug vehicle. Anodic oxidation is one of the cheapest and simplest approaches to obtain highly ordered nanotubes. Parameters such as applied potential, reaction time and fluoride containing in the electrolyte define the nanotubes morphology. However, the mechanical properties of the nanotubes layer do not have been completely elucidated and they play a crucial role in the implant long term stability. The objective of this research was to obtain TiO 2 nanotubes using anodic oxidation and to determine their elastic modulus and hardness. The TiO 2 nanotubes layer was obtained in a fluoride containing electrolyte for 1 hour, one group at 15 V and another one at 25 V. The TiO 2 nanotubes morphology was characterized by scanning electron microscopy (SEM) and atomic force microscopy (AFM). The elastic modulus and hardness were evaluated by nanoindentation experiments using a spherical tip. SEM images showed highly ordered nanotubes on all titanium surfaces and it was observed that the nanotubes diameters are directly related with the applied potential. Nanotubes diameters are 66 ± 9 nm and 131 ± 22 nm for nanotubes obtained at 15 V and 25 V, respectively. Nanoindentation test results showed a decrease in the elastic modulus comparing with titanium reference and these values approach to cortical bone elastic modulus. These results demonstrate that it was possible to obtain a homogeneous TiO 2 nanotubes layer that has mechanical properties adequate to improve implant long-term stability.
