“…Quaternary β Ti-based alloys are receiving significant consideration as medical implant materials due to their very low Young's modulus analogous to human bone and outstanding biocompatibility [ 290 ]. The main objective of emerging such alloys is to reduce Young's modulus disparity between the bone (10–30 GPa) and the medical implant, which enhances the load sharing between them [ 291 ].…”

“…In this regard, different quaternary alloys such as Ti–Nb–Ta–Zr alloys (including Ti–4Nb–4Ta–15Zr [ 292 ], Ti–29Nb–13Ta-4.6Zr [ 293 ], and Ti–35Nb–5Ta–7Zr [ 294 ]) were investigated. Among them, the Ti–35Nb–5Ta–7Zr possesses a lower elastic modulus (55 GPa) and thus is considered as one of the best options for medical implants [ 290 ]. However, works on the physicochemical, mechanical, and biological features of the MONs on such quaternary alloys are restricted [ 295 ].…”

Nanomedicine has seen a significant rise in the development of new research tools and clinically functional devices. In this regard, significant advances and new commercial applications are expected in the pharmaceutical and orthopedic industries. For advanced orthopedic implant technologies, appropriate nanoscale surface modifications are highly effective strategies and are widely studied in the literature for improving implant performance. It is well-established that implants with nanotubular surfaces show a drastic improvement in new bone creation and gene expression compared to implants without nanotopography. Nevertheless, the scientific and clinical understanding of mixed oxide nanotubes (MONs) and their potential applications, especially in biomedical applications are still in the early stages of development. This review aims to establish a credible platform for the current and future roles of MONs in nanomedicine, particularly in advanced orthopedic implants. We first introduce the concept of MONs and then discuss the preparation strategies. This is followed by a review of the recent advancement of MONs in biomedical applications, including mineralization abilities, biocompatibility, antibacterial activity, cell culture, and animal testing, as well as clinical possibilities. To conclude, we propose that the combination of nanotubular surface modification with incorporating sensor allows clinicians to precisely record patient data as a critical contributor to evidence-based medicine.

“…Among these available metal implants, the usage of titanium and its alloys in medicine has significantly increased due to their marvelous properties such as low density, high strength, high corrosion resistance, complete neutrality to the environment, high biocompatibility, low modulus and high capacity for bonding with bone and other tissues. Furthermore, since Ti alloys have lower modulus (55 to 110 GPa) in comparison to stainless steel 316 L (210 GPa) and Co-Cr alloys (240 GPa), their usage has increased in recent years [20]. While exposing to liquid in the body environment, metals and their alloys release metal ions from the implants and cause unwanted reactions in the body because of the chloride ions and highly aggressive proteins existence exposing to some materials having low corrosion resistance [3].…”

“…Although titanium alloy especially Ti-6Al-4 V alloy has great corrosion resistance and biocompatibility properties, the long-term performance of these alloys has made some concerns like releasing elements of Al and V from their implants that their releasing can cause problems and diseases like Alzheimer's and neuropathy [20][21][22]. Multilayer coatings have received specific attention in order to solve these problems.…”

The main goal of this study is to compare the electrochemical behavior of CrN/TiN multilayer coating and TiN single-layer coating applied by cathodic arc evaporation (CAE)-physical vapor deposition (PVD) on the substrate of Ti-6Al-4 V in Hank's solution. So, a TiN single-layer coating was formed using PVD method as well as CrN/TiN multilayer coating under totally the same conditions including deposition temperature, working pressure, bias voltage, cathode current and deposition time. To identify the phases in the coatings, X-ray diffraction (XRD) was utilized in order and field emission scanning electron microscopy (FE-SEM) was used in order to study the microstructure of coating. Potentiodynamic polarization (PDP) and electrochemical impedance spectroscopy (EIS) tests were also carried out for corrosion measurements. In the corrosion evaluation, the PDP and EIS tests were performed for the samples after immersion in Hank's solution for 24 hours to reach the steady state. The obtained results from PDP curves showed that the specimen with CrN/TiN multilayer coating exhibited better corrosion behavior than the TiN single-layer coatings. This improvement in corrosion resistance is probably due to the high density of the layers in the CrN/TiN multilayer coating that prevents the penetration of the corrosive solution to the substrate.

“…However, they are easy to dissolve and can undergo aseptic loosening in physiological environments due to the complex electrolyte environment in human bodily fluids, as well as the comprehensive action of active cells [2,5]. Furthermore, some studies have revealed that the corrosion and wear behavior of Ti-6Al-4V leads to the diffusion of aluminum and vanadium into the blood, causing local inflammation, allergies, poisoning, and diseases such as Alzheimer's disease [6,7]. In addition, the two-phase (α+β) Ti-6Al-4V has poorer corrosion resistance than the single-phase due to the galvanic coupling effect [8].…”

Corrosion and Tribocorrosion Behaviors for TA3 in Ringer’s Solution after Implantation of Nb Ions

Ti alloys are prone to corrosion and wear due to the hostile environment in bodily fluids, but the Ti-45Nb alloy is considered to be a promising titanium alloy with excellent biocompatibility and resistance to physiological corrosion. In this study, Nb ions were implanted into a TA3 alloy and the effect on the biological corrosion as well as tribocorrosion behavior of TA3 in Ringer’s solution was systematically investigated. The surface microstructure and XRD results revealed that the implanted samples showed a smoother surface due to the sputtering and radiation damages, and the Nb ions mainly existed in the alloy as the solid solution element. The electrochemical polarization tests showed that the implantation of Nb ions can increase the corrosion potential of the samples, showing a better thermodynamic stability. The tribocorrosion tests showed that the implanted samples exhibited a better thermodynamic stability in a corrosive environment accompanied by wear behavior, and the worn surface showed fewer pitting pits, indicating a better corrosion resistance. However, the abrasive wear and oxidation wear degree of the sample increased because of partial softening of the surface and brittle passivation film.
