“…Good corrosion resistance is a basic requirement of titanium alloy as a biomedical titanium alloy. Figure 15a summaries the reported self-corrosion current density of several titanium alloys in simulated body fluid against the elastic modulus [10,11,[26][27][28]. It can be concluded that TNZ-3Cu(T6) exhibited the lowest corrosion density and a low modulus among all these reported titanium alloys.…”

“…Figure 15b shows the elastic modulus of titanium alloys and the antibacterial rate of the alloy against S. aureus. Ti-13Nb-13Zr-10Cu [27], TNZ-3Cu, TNZ-5Cu [10], TNZ-7Cu, Ti-15Mo-10Ag [28] and Ti-13Nb-13Zr-13Ag [11] alloys all have low elastic modulus and good antibacterial effect. However, with the consideration of corrosion resistance in Figure 15b, TNZ-3Cu exhibited good comprehensive properties: low elastic modulus, very good corrosion resistance, and acceptable antibacterial property.…”

“…More recently, Cu or Ag was introduced into β or near β titanium in order to obtain a new titanium alloy with low modulus and good antibacterial performance. Shi et al [10] reported the addition of 5 wt.% Cu clearly improved the antibacterial effect of Ti-13Nb-13Zr-5Cu (92.7% reduction); however, the elastic modulus of the alloy was increased from 65 GPa to 82 GPa because of the precipitation of Ti 2 Cu phase and α" phase. Cai et al [11] found that antibacterial rate of TNZ was improved to 98% by adding 13 wt.% Ag, but the presence of Ti2Ag phase and α phase also increased the elastic modulus from 75 GPa to 82 GPa.…”

Device-related infection or inflammatory and stress shield are still the main problems faced by titanium alloy implants for long-term implantation application; therefore, it is of great significance to design an alloy with low elastic modulus and good antibacterial properties as well as good biocompatibility. In this paper, Ti-13Nb-13Zr-xCu(x = 3, 7 wt.%) alloys were designed and prepared to reveal the influence of Cu content on the elastic modulus and antibacterial property. X-ray diffractometer, metallographic microscope, scanning electron microscope, and transmission electron microscope were used to study the phase transformation, microstructure, mechanical properties, antibacterial properties, and cytotoxicity of the alloys. The experimental results have demonstrated that the antibacterial performance and the elastic modulus were significantly improved but the corrosion resistance deteriorated with the increase of the copper content. Ti-13Nb-13Zr-3Cu with a low modulus of 73 GPa and an antibacterial rate of over 90% against Staphylococcus aureus (S. aureus) exhibited great potential as a candidate for implant titanium in the future.

“…Shi et al [105] fabricated a low elastic modulus Ti-13Nb-13Zr-5Cu alloy with a good antibacterial property (against S. aureus > 90%) as the precipitation of the Ti 2 Cu phase. Liu et al [106] prepared SLA-TiCu by sandblasting and large-grits etching (SLA) to avoid implant-related infection and promote early bone integration.…”

Ti and Ti alloys have charming comprehensive properties (high specific strength, strong corrosion resistance, and excellent biocompatibility) that make them the ideal choice in orthopedic and dental applications, especially in the particular fabrication of orthopedic and dental implants. However, these alloys present some shortcomings, specifically elastic modulus, wear, corrosion, and biological performance. Beta-titanium (β-Ti) alloys have been studied as low elastic modulus and low toxic or non-toxic elements. The present work summarizes the improvements of the properties systematically (elastic modulus, hardness, wear resistance, corrosion resistance, antibacterial property, and bone regeneration) for β-Ti alloys via surface modification to address these shortcomings. Additionally, the shortcomings and prospects of the present research are put forward. β-Ti alloys have potential regarding implants in biomedical fields.

The different thickness (Fe/Pd)n coatings were prepared by vacuum ion plating technology on a pure Ti substrate. The (Fe/Pd)n coatings were magnetized using an MC-4000 high-pressure magnetizing machine. Then, the effect of the (Fe/Pd)n coating thickness on the magnetic properties was studied. The surface and section morphology, composition, phase structure, magnetic properties, and biocompatibility of the (Fe/Pd)n coatings were studied by scanning electron microscopy, X-ray diffraction, energy-dispersive X-ray spectroscopy, and CCTC-1 digital flux field measurement. The results showed that the (Fe/Pd)n coatings were granular, smooth, and compact, without cracks. In addition the (Fe/Pd)n coatings formed an L10 phase with a magnetic face-centered tetragonal-ordered structure after heat treatment. With the increase in the thickness of (FePd)n coatings, the content of L10 FePd phase increased and the remanence increased. The remanence values of the Fe/Pd, (Fe/Pd)5, (Fe/Pd)10, and (Fe/Pd)15 magnetic coatings were 0.83 Gs, 5.52 Gs, 7.14 Gs, and 7.94 Gs, respectively. Additionally, the (Fe/Pd)n magnetic coatings showed good blood compatibility and histocompatibility.
