“…TiNbSn alloys have a uniform surface corrosion which provides a passive film which can be formed by Ti 2 O 3 , TiO 2 , Nb 2 O 5 and SnO 2 [12,13]. Several studies have demonstrated that TiNbSn alloys have lower Young's modulus than the Ti alloys which reduces the stress shielding phenomena [3,4,14]. Kuroda et al compared TiNbTaSn alloys [5], showing that the alloy containing 2% wt.…”

“…Many β-type alloys composed by Nb, Ta, Zr, Mo, Hf, Au, Pd, Pt, Ag, Ga, Ge, Sc and Sn were developed in the last two decades [13]. One recently developed promising biomedical alloy, Ti3Zr2Sn3Mo25Nb shows significant improvement of the corrosion resistance and biocompatibility compared to previous generation of Ti alloys such as CP Ti and Ti6Al4V [14]. Liu et al [15] studied the in vitro effects of some alloying elements, including the Sn on pure iron and they obtained that there was not significant cytotoxicity to ECV304 cells, except for the FeMn alloy.…”

The electrochemical behaviour of three different near-β titanium alloys (composed by Ti, Nb and Sn) obtained by powder metallurgy for biomedical applications has been investigated. Different electrochemical and microscopy techniques were used to study the influence of the chemical composition (Sn content) and the applied potential on the microstructure and the corrosion mechanisms of those titanium alloys. Addition of Sn below 4% wt. to the titanium powder improves the microstructural homogeneity and generates an alloy with high corrosion resistance with low elastic modulus, being more suitable as a biomaterial. When the Sn content is above 4%, the corrosion resistance considerably decreases by increasing the passive dissolution rate; this effect is enhanced with the applied potential.

“…of Sn increases the corrosion resistance and decreases the elastic modulus and the porosity of the alloy. Related to the citotoxicity of similar Ti-Nb-Sn alloys, there are many studies that confirmed they are suitable biomaterials due to their good cell adhesion or cell substrate interaction, thus they do not cause toxic effects [16][17][18][19][20].…”

ElsevierGuiñon Pina, V.; Dalmau, A.; Amigó Borrás, V. (2015). AbstractThe tribo-electrochemical behavior of different  titanium alloys for biomedical applications sintered by powder metallurgy has been investigated. Different mechanical, electrochemical and optical techniques were used to study the influence of the chemical composition, Sn content, and the electrochemical conditions on the tribocorrosion behavior of those alloys Ti30NbxSn alloys (where "x" is the weight percentage of Sn content, 2% and 4%).Sn content increases the active and passive dissolution rate of the titanium alloys, thus increasing the mechanically activated corrosion under tribocorrosion conditions. It also increases the mechanical wear of the alloy. Prevailing electrochemical conditions between -1 and 2 V influences the wear accelerated corrosion by increasing it with the applied potential and slightly increases the mechanical wear of Ti30Nb4Sn.Wear accelerated corrosion can be predicted by existing models as a function of electrochemical and mechanical parameters of the titanium alloys.

“…These alloys have lower elasticity modulus, higher strength, excellent corrosion resistance, and better toughness to compar with the a and a?b titanium alloys [9,10]. Hence, a metastable b titanium alloy, Ti-25Nb-3Mo-3Zr-2Sn (TLM) containing the nontoxic elements Nb, Zr, Mo, and Sn, was developed as biomedical material, which is suitable for implant applications [12][13][14][15][16]. The TLM alloy exhibits significant improvement in these properties compared to the previous generation titanium alloys, such as C.P.…”

Wear and Electrochemical Corrosion Behavior of Biomedical Ti–25Nb–3Mo–3Zr–2Sn Alloy in Simulated Physiological Solutions

The wear and electrochemical corrosion behavior of the biomedical Ti-25Nb-3Mo-3Zr-2Sn (TLM) titanium alloy was investigated in various simulated physiological solutions. Different simulated physiological solutions comprised phosphate-buffered solution (PBS), PBS with bovine serum albumin (PBS?BSA), and PBS with hyaluronic acid (PBS?HA) were employed. A potentiostat and a reciprocating friction and wear tester were used to study the wear and corrosion behavior of the TLM alloy. The influence of the chemical composition of the simulated solutions on the tribo-electrochemical behavior was considered by potentiodynamic studies under reciprocating friction and wear conditions. It was found that the corrosion tendency of the TLM alloy was the most obvious in PBS?HA under static corrosion condition, while it was just opposite with wear. Compared with static corrosion, the corrosion resistance of the TLM alloy was decreased with sliding conditions. The values of i corr were two orders of magnitude higher than those at static corrosion. This phenomenon shows that the wear accelerated corrosion. Under coexisting condition of both electrochemical corrosion and wear, the wear rate of the TLM alloy mutually influenced by both factors will be accelerated. Plastic grooves and deformation were observed on the worn surfaces of the TLM alloy by scanning electron microscopy (SEM). Through the observation of SEM, the tribological mechanism was a typical corrosive wear, and the main wear mechanisms were abrasive with adhesive wear under the interaction between corrosion and wear. The XPS results show that the passive films include the TiO
