“…This is evidenced by the change in the diffraction patterns of the samples after PIB irradiation, on which the disappearance of the β-phase reflections and the broadening of the α-phase reflections are observed, and onto which the α"-phase reflections can be superimposed ( Figure 6). Similar changes in the phase composition of the samples after irradiation with pulsed particle beams were previously observed for the cast Ti-6Al-4V alloy [36]. The formation of the α"-martensite phase in thin surface layers (Figures 4 and 6) is caused by the fact that the formation of the α"-phase requires significantly less atomic displacements compared to the formation of the α'-phase.…”

“…The redistribution of the concentration of alloying elements, the formation of martensitic phases, and an increase in the dispersion of the structure affect the level of plastic and strength characteristics. The presence of a gradient microstructure along the depth of the material surface layer can provide a better combination of mechanical properties in comparison to materials with a homogeneous structure [36,44]. In the present work, it was found that the exposure of PIB leads to an increase in the values of microand nanohardness, which is caused by the formation of a gradient nanostructured state (Figure 4) and the formation of a metastable phase α'.…”

“…This is due to its ability to modify surface layers without changing the physicochemical state of the materials in the bulk of the parts. The effectiveness of the application of powerful pulsed ion beams and ion implantation for processing products from titanium and its alloys has already been proven in many works [23][24][25][26][27][28][29][30][31][32][33][34][35][36]. It was shown that, as a result of pulsed ion beam exposure, it is possible to reduce surface roughness [23], form a gradient microstructure [26,27], increase mechanical properties [28][29][30][31][32][33], and improve corrosion resistance [34,35].…”

“…At the same time, the process of material surface treatment by pulsed ion beam is also characterized by a number of limitations. For example, it is quite difficult to apply this type of processing to samples with complex geometry; in addition, during pulsed charged particle beam treatment of internal surfaces, serious technological problems often arise [36].…”

The effect of surface modification of Ti-6Al-4V samples manufactured by electron beam melting (EBM) using a pulsed carbon ion beam is studied in the present work. Based on the results of XRD, SEM, and TEM analysis, patterns of changes in the microstructure and phase composition of the EBM Ti-6Al-4V alloy, depending on the number of pulses of pulsed ion beam exposure, are revealed. It was found that gradient microstructure is formed as a result of pulsed ion beam irradiation of the EBM Ti-6Al-4V samples. The microstructure of the surface layer up to 300 nm thick is represented by the (α + α”) phase. At depths of 0.3 μm, the microstructure is mixed and contains alpha-phase plates and needle-shaped martensite. The mechanical properties were investigated using methods of uniaxial tensile tests, micro- and nanohardness measurements, and tribological tests. It was shown that surface modification by a pulsed ion beam at an energy density of 1.92 J/cm2 and five pulses leads to an increase in the micro- and nanohardness of the surface layers, a decrease in the wear rate, and a slight rise in the plasticity of EBM Ti-6Al-4V alloy.

Commercially pure titanium and titanium alloys have been among the most commonly used materials for biomedical applications since the 1950s. Due to the excellent mechanical tribological properties, corrosion resistance, biocompatibility, and antibacterial properties of titanium, it is getting much attention as a biomaterial for implants. Furthermore, titanium promotes osseointegration without any additional adhesives by physically bonding with the living bone at the implant site. These properties are crucial for producing high-strength metallic alloys for biomedical applications. Titanium alloys are manufactured into the three types of α, β, and α + β. The scientific and clinical understanding of titanium and its potential applications, especially in the biomedical field, are still in the early stages. This review aims to establish a credible platform for the current and future roles of titanium in biomedicine. We first explore the developmental history of titanium. Then, we review the recent advancement of the utility of titanium in diverse biomedical areas, its functional properties, mechanisms of biocompatibility, host tissue responses, and various relevant antimicrobial strategies. Future research will be directed toward advanced manufacturing technologies, such as powder-based additive manufacturing, electron beam melting and laser melting deposition, as well as analyzing the effects of alloying elements on the biocompatibility, corrosion resistance, and mechanical properties of titanium. Moreover, the role of titania nanotubes in regenerative medicine and nanomedicine applications, such as localized drug delivery system, immunomodulatory agents, antibacterial agents, and hemocompatibility, is investigated, and the paper concludes with the future outlook of titanium alloys as biomaterials.
