“…The corrosion current density (J corr ) and corrosion potential (E corr ) were obtained using Tafel extrapolation. As is well known, a lower J corr and a higher E corr indicate greater corrosion resistance [67]. As demonstrated in Figure 12A and Table 2, the E corr of the SH-35 V displays a significantly positive shift from −0.319 V to −0.214 V and the corresponding J corr (6.427 × 10 −9 A•cm −2 ) is reduced by one order of magnitude as compared to that of bare Ti, suggesting its good corrosion inhibition.…”

Titanium and its alloys have been widely employed as dental implant materials. However, polymicrobial infection is still one of the most common reasons for implant failure, which has already become a worldwide problem and poses a threat to human health. In this study, a titanium-based (Ti-based) superhydrophobic coating was effectively created by anodization followed by hydrophobic modification of 1H,1H,2H,2H-perfluorodecyltriethoxysilane (FAS), which shows a high water contact angle (WCA) of 159.9 ± 5.8° and a low water sliding angle (WSA) of 2.7 ± 2.2°. The thickness of the anodized samples is from 500 nm to 4 µm as the anodizing voltage increases. The Ti-based superhydrophobic coating demonstrated the existence of Ti, O, C, F, and Si elements, and the corresponding phase compositions are Ti and anatase. The results showed that the Ti-based superhydrophobic coating has good biocompatibility to co-culture with L929 cells for 1, 3, and 5 days. It was also proven that the as-prepared Ti-based superhydrophobic coating has enhanced antibacterial abilities against Staphylococcus aureus (S. aureus) and Porphyromonas gingivalis (P. gingivalis, P.g) after 4, 12, and 24 h. Moreover, the Ti-based superhydrophobic coating can significantly reduce platelet adhesion and activation. In addition, the Ti-based superhydrophobic coating also exhibits a considerable positive shift in the corrosion potential (Ecorr) and a decline of one order of magnitude in the corrosion current density (Jcorr), showing good anticorrosive properties. It was also found that the capsule around the Ti-based superhydrophobic coating was thinner than that of bare Ti after implantation for 7, 15, and 28 days, indicating its good biosafety. Therefore, the as-prepared Ti-based superhydrophobic coating can be a suitable candidate for Ti-based implants in dental applications.

“…The coating surface can also facilitate formation of a layer of calcium phosphate, thereby mimicking the natural composition of bone and promoting osseointegration. 53,54 Apatite formation on the coating surface was due to the presence of Fe 3 O 4 . Fe 3 O 4 hydrolyzed to form Fe-OH, which encouraged the heterogeneous nucleation of calcium phosphate in SBF.…”

“…In addition, as previous reports described, the laser microgroove parameters might significantly affect the surface performance. 5 , 24 Several studies 25 − 28 indicated that the widths of microgrooves had an important effect on the wear resistance, corrosion resistance, and cell response of the material surface, and they pointed out that the difference in mechanical properties and the microstructure crystal phase structure are the main factors affecting surface properties. Bhaduri et al 29 reported that the groove arrays with a width of 40 um effectively improved the tribological performance on tungsten carbide (WC) blocks.…”

The poor biotribological properties and bioinertness of Ti6Al4V have restricted its application in biomedical materials. In this study, microgrooves of different widths were prepared on the surface of a Ti6Al4V alloy by laser treatment. The tribological properties under dry lubrication and simulated body fluid (SBF) lubrication conditions, the electrochemical corrosion properties in SBF solution, and the bone marrow mesenchymal stem cell (BMSC) behavior on the surfaces were systematically tested. The corresponding mechanisms were discussed. The results showed that Ti6Al4V with a microgroove width of 45 μm (Ti64-45) exhibited excellent wear resistance with decreasing wear rates of 89.79 and 85.43% under dry friction and SBF lubrication compared to the Ti64 sample, which might be due to the increase of surface microhardness. Moreover, the excellent anticorrosion performance of Ti64-45 was attributed to the grain refinement on the titanium alloy surface with a lower volume fraction ratio of β phase to α phase. In addition, the microgrooves with a width of 45 μm are more conducive to BMSC proliferation and adhesion, related to promoting cell signal transduction due to cell extrusion. These studies imply that the microgroove structures are potential for application in the medical field.
