“…(Ti‐40Nb)‐4In and reference Ti‐40Nb (wt %) alloy specimen in rod shape with 10 mm diameter and 100 mm length were prepared using a multi‐step casting process and subsequent annealing and water quenching. Details on the chemical and microstructural characterization of the Ti‐40Nb‐4In and Ti‐40Nb alloys has been previously reported elsewhere …”

“…Metal release studies were conducted based on DIN EN ISO 10993–15 . A complex concentrated simulated body fluid, for example, Ringer's solution, does not allow a reliable metal ion trace concentration analysis in solution with inductively coupled plasma optical emission spectrometry (ICP‐OES). Therefore, TBS solution at pH levels of 7.6 and 2.0 was used for metal ion release analysis.…”

“…Pure In exhibits in Ringer's solution severe active dissolution. However, the small addition of 4 wt % In to Ti‐40Nb only slightly alters the properties of anodically grown passive films by incorporation of In(OH) 3 /In 2 O 3 traces in these barrier films composed of Ti‐ and Nb‐oxides …”

Small indium (In) additions up to 5 wt % to the beta-type Ti-40Nb alloy effectively improve its mechanical biofunctionality. The impact on its biocompatibility is addressed in this work. Comparative electrochemical polarization studies and inductively coupled plasma optical emission spectrometry analyses were conducted in Tris-buffered saline (on the basis of 150 mM NaCl) with pH 7.6 and 2.0 at 310 ± 1 K with Ti-6Al-4V as reference. The metal ion releases from beta-type alloys were generally very low, for example, those of In ions from (Ti-40Nb)-4In specimens were below 6 × 10 mmol/cm . X-ray photoelectron spectroscopy revealed the passivation mainly by Ti- and Nb-oxides with traces of In-oxides as the dominating surface process. In vitro studies demonstrate a better human bone marrow stromal cells (hBMSC) activity on the beta-type alloys in comparison to CP-Ti (grade 2), which is mainly due to their high Nb content. At 24 h after seeding on (Ti-40Nb)-4In the metabolic activity of hBMSC was 1.5-fold higher and after 11 days, the tissue non-specific alkaline phosphatase activity was 1.8-fold higher relative to values for CP-Ti. Surface treatments, like chemical etching or plasma oxidation, change the surface topography and the thickness and composition of the oxide layers, but they are not effective in further improving the cell response. © 2017 Wiley Periodicals, Inc.

“…Chemical composition is a major parameter which can influence the corrosion resistance of titanium alloys including new beta type titanium alloys. For instance, small additions of indium (In) to a beta-type Ti-Nb alloy (tested in Ringer's solution) do not yield any negative effect on the corrosion behaviour and it was reported that a further addition of indium will enhance the corrosion resistance of the alloy [68]. Further addition of ruthenium (Ru) to Ti-20Nb-xRu (x = 0, 0.5, 1.0, 1.5 at.…”

“…TNTZ showed two time constants at higher potentials, indicating the presence of two passive layers, namely an inner layer for corrosion resistance and an outer porous layer. Therefore, TNTZ seems to act better in orthopaedic applications [68]. Many authors have delved deeply in the electrochemical properties of low modulus Ti alloys including beta phase [71][72][73][74][75][76][77].…”

The corrosion behaviour of new generation titanium alloys (β-type with low modulus) for medical implant applications is of paramount importance due to their possible detrimental effects in the human body such as release of toxic metal ions and corrosion products. In spite of remarkable advances in improving the mechanical properties and reducing the elastic modulus, limited studies have been done on the electrochemical corrosion behaviour of various types of low modulus titanium alloys including the effect of different beta-stabilizer alloying elements. This development should aim for a good balance between mechanical properties, design features, metallurgical aspects and, importantly, corrosion resistance. In this article, we review several significant factors that can influence the corrosion resistance of new-generation titanium alloys such as fabrication process, body electrolyte properties, mechanical treatments, alloying composition, surface passive layer, and constituent phases. The essential factors and their critical features are discussed. The impact of various amounts of α and β phases in the microstructure, their interactions, and their dissolution rates on the surface passive layer and bulk corrosion behaviour are reviewed and discussed in detail. In addition, the importance of different corrosion types for various medical implant applications is addressed in order to specify the significance of every corrosion phenomenon in medical implants.
