“…Titanium alloys are chemically active and have high ductility, giving rise to a strong tendency for adhesion. 30 When the titanium alloy surface undergoes wear, it experiences severe deformation. Once the yield strength is surpassed, plastic deformation occurs on the material's surface and accumulates during repeated contact.…”

The tribocorrosion of titanium implants is the primary cause of their late failure. As the most promising third-generation medical β-type titanium alloy, Ti-13Nb-13Zr (TC26) demonstrates superior corrosion resistance and harmless chemical element composition, making it an excellent alternative to Ti-6Al-4V alloy (TC4). Nonetheless, this study has revealed a significant weakness of TC26 in tribocorrosion properties under low dissolved oxygen concentration conditions, which could pose potential hazards in subsequent medical applications. The effects of low dissolved oxygen concentration on the tribocorrosion properties and ion release were examined using electrochemical methods, laser confocal microscopy, scanning electron microscopy, and inductively coupled plasma emission spectrometer. The findings indicate that TC26 exhibits significantly inferior corrosion resistance compared to TC4 due to the sluggish recovery rate of the passivation film under low dissolved oxygen concentration conditions during wear. Moreover, TC26 experiences greater mechanical wear loss than that of TC4. However, under the synergistic effect of wear and corrosion, TC26 releases a minimal amount of ions, while excessive harmful Al ions are released by TC4.

“…In this paper, the root shape of the tooth was used as the study object, and the pore size should be greater than 300 μm, considering the need to promote the generation of new bone and capillaries [ 30 ]. Jetté et al, after analyzing the pore size through static testing (2018), suggested that the porosity should be between 40% and 70% when designing porous structures [ 13 ].…”

Porous structures can reduce the elastic modulus of implants, decrease stress shielding, and avoid bone loss in the alveolar bone and aseptic loosening of implants; however, there is a mismatch between yield strength and elastic modulus as well as biocompatibility problems. This study aimed to investigate the parametric design method of porous root-shaped implants to reduce the stress-shielding effect and improve the biocompatibility and long-term stability and effectiveness of the implants. Firstly, the porous structure part was parametrically designed, and the control of porosity gradient distribution was achieved by using the fitting relationship between porosity and bias and the position function of bias. In addition, the optimal distribution law of the porous structure was explored through mechanical and hydrodynamic analyses of the porous structure. Finally, the biomechanical properties were verified using simulated implant–bone tissue interface micromotion values. The results showed that the effects of marginal and central porosity on yield strength were linear, with the elastic modulus decreasing from 18.9 to 10.1 GPa in the range of 20–35% for marginal porosity, with a maximum decrease of 46.6%; the changes in the central porosity had a more consistent effect on the elastic modulus, ranging from 18.9 to 15.3 GPa in the range of 50–90%, with a maximum downward shift of 19%. The central porosity had a more significant effect on permeability, ranging from 1.9 × 10−7 m2 to 4.9 × 10−7 m2 with a maximum enhancement of 61.2%. The analysis showed that the edge structure had a more substantial impact on the mechanical properties. The central structure could increase the permeability more effectively. Hence, the porous structure with reasonable gradient distribution had a better match between mechanical properties and flow properties. The simulated implantation results showed that the porous implant with proper porosity gradient distribution had better biomechanical properties.

“…Density and hardness are two important properties that should be considered during assessing the wear and corrosion performances of metallic materials. [27][28][29] Thus, the density and hardness of CP-Ti fabricated using two different feedstocks and forged TC4 alloy were tested and evaluated first (Figure 2). It can be found that the relative density of all samples was higher than 99% and can be considered to close fully dense.…”

Herein, commercially pure titanium parts (CP‐Ti) are fabricated successfully by laser powder bed fusion using cost‐effective ball milling (BM) near‐spherical powder. The hardness, microstructure, wear, and corrosion performances of BM‐Ti parts are investigated systemically. The microstructure of the fabricated BM‐Ti sample consists of α′ phase. Compared with the sample fabricated using gas‐atomized (GA) spherical powder, the BM‐Ti sample exhibits higher hardness (354 HV vs 240 HV) due to grain refinement. Owing to the formation of a denser oxide film and finger gain, BM‐Ti exhibits a higher corrosion resistance than that of GA‐Ti and forged Ti–6Al–4 V alloy. Under the same load, taking 2 N for example, the BM‐Ti sample exhibits a lower wear rate (1.03 × 10−12 m3 N−1 m−1) than that of the GA‐Ti sample (1.75 × 10−12 m3 N−1 m−1), and comparable to the forged Ti–6Al–4 V alloy (0.84 × 10−12 m3 N−1 m−1). The wear mechanism of the BM‐Ti sample and forged Ti–6Al–4 V alloy is abrasive wear accompanied by adhesion, while the mechanism for the GA‐Ti sample is a combination of delamination and adhesion wear. Together, enhanced wear and corrosion performances of CP‐Ti fabricated using low‐cost BM near‐spherical powder widen its applications in the fields of biomedical further.
