Biocompatibility of Anodized Low-Cost Ti-4.7Mo-4.5Fe Alloy

Abstract:

Self-organized TiO₂ nanotubes were generated on the surface of the designed alloy Ti-4.7Mo-4.5Fe (TMF55) by electrochemical anodization process to investigate the effect of nanostructured on the biocompatibility. The biocompatibility of the designed alloys showed very promising results compared to those of Ti-6Al-4V ELI alloy, especially for the untreated and nanostructured surfaces of the specimens with diameter size less than 35 nm. By increasing the diameter of nanotube, the biocompatibility is decreased. The most convenient compatible alloy was in favor of TMF8 alloy, making this V-free low-cost alloy is a promising candidate for replacing the commercial Ti-6Al-4V ELI alloy in biomedical applications. Keywords: Self-organized TiO₂ nanotubes, biocompatibility, Titanium alloys, Cell Counting Kit-8, WST-8 assay.
