“…In addition, Ti-6Al-4V contains aluminum (Al) and vanadium (V) that are harmful to the human body [4,5]. In recent years, many β-type Ti alloys with low elastic modulus and without Al and V elements have been widely developed, such as Ti-5Nb-5Mo [6,7], Ti-26Zr-24Nb [8], Ti-Nb-Zr-Fe--O [9], Ti-Nb-Ta-O [10], Ti-20Nb-5Ag [11], and Ti-4Fe [12]. Ti-Nb-Sn alloys have been proven to have *Corresponding author: tel.…”

In this work, different thermomechanical treatment conditions were used to improve the mechanical performances of Ti-25Nb-8Sn. During cold rolling treatment (50, 75, and 90 %), as-cast Ti-25Nb-8Sn underwent a stress-induced phase transformation from a single β phase to a three-phase structure of α + β + ωstr. After the subsequent aging treatment, Ti-25Nb--8Sn presents three-phase β + α + ωiso (at 250 and 400 • C, for 30 min) and two-phase β + α (at 600 • C, for 30 min). At lower aging temperatures (250 and 400 • C), yield strength/modulus (× 1000) ratios of Ti-25Nb-8Sn are dramatically improved with a maximum increase of 143 %, from 9.06 (as-cast) to 16.2-22.0. Under various thermomechanical treatment conditions in this study, the results show that Ti-25Nb-8Sn has excellent yield strength/modulus (× 1000) ratio (∼ 22) and corrosion resistance after 90 % cold rolling and subsequent aging treatment at 250 and 400 • C for 30 min.

“…Although corrosion and wear-related problems have been recognized as a major issue impeding their long-term application, there is still a lack of knowledge about the basic underlying mechanisms [11]. Moreover, it is well-known that microstructure and alloy composition drive the mechanical and corrosion behaviour of any given alloy [12][13][14][15][16]. However, the microstructural features of implants may vary broadly due to chemical composition and different manufacturing processes applied.…”

Titanium alloys, especially Ti6Al4V, are commonly applied in orthopaedic implants as a result of their relatively low density, good corrosion properties, satisfactory biocompatibility and bone ingrowth promoting properties. However, Ti implants are susceptible to mechanical failure. Although corrosion and wear related problems have been recognized as a major issue impeding their long-term application, there is still a lack of knowledge about the basic mechanisms. Previously, the tribocorrosion properties of 4 distinct titanium alloys (Ti13Nb13Zr, Ti12Mo6Zr2Fe, Ti29Nb13Ta4.6Zr aged at 300 °C and at 400 °C) was analysed in the published Part I of this study in regard to wear rates, electrochemical behaviour, and the tribocorrosion synergism estimations. This work, Part II, contributes to the previous study and investigates the tested surfaces of these 4 Titanium alloys from the same tribosystem aiming to characterize the wear track surfaces and identify the main wear mechanism, to characterize the tribofilm and to investigate the subsurface alterations occurring under varying contact pressures and electrochemical potentials. The results indicated a dominant abrasion wear mechanism regardless of microstructure, electrochemical potential and normal load (contact pressure). Additionally, grain refinement observed on the subsurface varied with alloy and electrochemical potential, with the variation being mostly independent of alloy microstructure. Finally, a graphitic tribofilm was detected in most conditions, which while inconsequential in regard to wear, may explain the previously observed reduction of friction. Graphic Abstract
