“…High purity titanium foils were anodised in mixtures of H 2 SO 4 and H 3 PO 4 at varying voltages (100 V, 140 V, 180 V, and 200 V). They found that a more porous, rougher, and higher crystallinity oxide layer was obtained at the applied voltage of 200 V and these results match observations in other studies [ 19 , 28 , 64 , 66 , 67 , 68 , 69 , 70 , 71 , 72 , 73 ]. In the case of fabrication of TiO 2 nanotubes, low voltages (5–60 V) were applied during anodic oxidation.…”

“…Generally, nitric acid, hydrofluoric acid, and acetone are all used for polishing, alkaline cleaning, and acid activation. One of the ultimate functions of these processes is to remove the native oxide layer and contaminants that are present on the titanium substrate when it was exposed to air at room temperature [63,64,65,66,67,68].…”

Anodised titanium has a long history as a coating structure for implants due to its bioactive and ossified surface, which promotes rapid bone integration. In response to the growing literature on anodised titanium, this article is the first to revisit the evolution of anodised titanium as an implant coating. The review reports the process and mechanisms for the engineering of distinctive anodised titanium structures, the significant factors influencing the mechanisms of its formation, bioactivity, as well as recent pre-and post-surface treatments proposed to improve the performance of anodised titanium. The review then broadens the discussion to include future functional trends of anodised titanium, ranging from the provision of higher surface energy interactions in the design of biocomposite coatings (template stencil interface for mechanical interlock) to techniques for measuring the boneto-implant contact (BIC), each with their own challenges. Overall, this paper provides up-to-date information on the impacts of the structure and function of anodised titanium as an implant coating in vitro and in/ex vivo tests, as well as the four key future challenges that are important for its clinical translations, namely (i) techniques to enhance the mechanical stability and (ii) testing techniques to measure the mechanical stability of anodised titanium, (iii) real-time/in-situ detection methods for surface reactions, and (iv) cost-effectiveness for anodised titanium and its safety as a bone implant coating.

“…Based on the improvement of 316L BSS implants, an electrochemical anodizing process was adopted as a surface treatment method to modify the 316L BSS in this study. Previous studies by our research team have reported that the anodized titanium with a hierarchical porous (micro and nanoporous) surface possessed great potential to enhance cell adhesion ability [18,19]. Accordingly, the potential anodizing method could be utilized to fabricate a promising hierarchical porous surface on the 316L BSS implant to promote biocompatibility.…”

In this study, an electrochemical anodizing method was applied as surface modification of the 316L biomedical stainless steel (BSS). The surface properties, microstructural characteristics, and biocompatibility responses of the anodized 316L BSS specimens were elucidated through scanning electron microscopy, X-ray photoelectron spectroscopy, X-ray diffractometry, transmission electron microscopy, and in vitro cell culture assay. Analytical results revealed that the oxide layer of dichromium trioxide (Cr2O3) was formed on the modified 316L BSS specimens after the different anodization modifications. Moreover, a dual porous (micro/nanoporous) topography can also be discovered on the surface of the modified 316L BSS specimens. The microstructure of the anodized oxide layer was composed of amorphous austenite phase and nano-Cr2O3. Furthermore, in vitro cell culture assay also demonstrated that the osteoblast-like cells (MG-63) on the anodized 316L BSS specimens were completely adhered and covered as compared with the unmodified 316L BSS specimen. As a result, the anodized 316L BSS with a dual porous (micro/nanoporous) oxide layer has great potential to induce cell adhesion and promote bone formation.
