“…Owing to the different morphologies and crystal structures of the TNTs, the resulting mechanical properties varied. Other previous studies reached similar conclusions on the mechanical stability of TNTs [ 180 , 292 , 297 , 298 ].…”

“…They proved that with an increase of positive voltage, the MAO coatings obtained from the CaP-based electrolytes show good surface stability, and the micro-morphology of the coatings is smoother than that obtained from the silicate-based electrolytes [338]. As for TNTs, recent comprehensive study Çaha et al [298] clarified that the fabrication of a mechanically stable TNTs via multilayer anodising process is highly demanding, but their proposed AO double-stage route is facile and the optimised TNTs stability was tested using reliable techniques without compromising the integrity of the coating. Their proposed TNTs stability enhancements was confirmed to be significant based on data from coating adhesion, hardness and corrosion complemented with tribo-mechanical performances [298], whereas similar findings were reported elsewhere [287,290,314].…”

Overall, Figure 9 represents the recent optimised design of anodised titanium as a coating on commercial implants, which is biocompatible and mechanically stable with increased bioactivity in vitro and in/ex vivo compared to other comparable coating structure such as sandblasted and acid-etched Ti surfaces [317,324].…”

“…The production process of anodised titanium via two-step AO is now common practice in order to produce a bio-functionalised and reliable passivation of TiO 2 with higher degrees of mechanical stability [92,93,164,298,320,355,356]. Bartkowiak et al [355] suggested a U-shaped layering of TNTs derived from two-step anodisation produced a highly adherent TNTs to the substrate.…”

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.
