“…These results are in agreement with others works; Naofumi et al [55] found that the amount of S, B and P incorporated into coatings obtained on Ti depends on the concentration of the electrolyte used, and they also conclude that these species inhibited the crystallization of the coatings. On the other side, Cui et al [56] reported the formation of amorphous anodic coatings on Ti in 2 M H3PO4 electrolyte at 100, 150…”

Titanium (Ti) is a material frequently used in orthopedic applications, due to its good mechanical properties and high corrosion resistance. However, formation of a non-adherent fibrous tissue between material and bone drastically could affect the osseointegration process and, therefore, the mechanical stability of the implant. Modifications of topography and configuration of the tissue/ material interface is one of the mechanisms to improve that process by manipulating parameters such as morphology and roughness. There are different techniques that can be used to modify the titanium surface; plasma electrolytic oxidation (PEO) is one of those alternatives, which consists of obtaining porous anodic coatings by controlling parameters such as voltage, current, anodizing solution and time of the reaction. From all of the above factors, and based on previous studies that demonstrated that bone cells sense substrates features to grow new tissue, in this work commercially pure Ti (c.p Ti) and Ti6Al4V alloy samples were modified at their surface by PEO in different anodizing solutions composed of H2SO4 and H3PO4 mixtures. Treated surfaces were characterized and used as platforms to grow osteoblasts; subsequently, cell behavior parameters like adhesion, proliferation and differentiation were also studied. Although the results showed no significant differences in proliferation, differentiation and cell biological activity, overall results showed an important influence of topography of the modified surfaces compared with polished untreated surfaces. Finally, this study offers an alternative protocol to modify surfaces of Ti and their alloys in a controlled and reproducible way in which biocompatibility of the material is not compromised and osseointegration would be improved.

“…A number of studies investigated the effect of anodic oxidation on the osteoconductivity of titanium. Anodic films on titanium that consisted of rutile and/or anatase phases with porous structures showed an increased apatite-forming ability in a simulated body solution compared to amorphous titania surfaces 1,19,20) . Surface morphology plays a fundamental role in cell behavior.…”

“…Titanium and its alloys have been successfully used as biomaterials since they were introduced more than fifty years ago, thanks to their good mechanical properties, corrosion resistance and biocompatibility with living tissues [1][2][3][4] . As commercially pure titanium (CP-Ti) has relatively lower fatigue strength, titanium alloys such as Ti6Al4V have widely been used to overcome this disadvantage of CP-Ti for heavy load [5][6][7] .…”

Anodic oxidation is used for the surface treatment of commercial implants to improve their functional properties for clinical success. Here we conducted ultrastructural and chemical investigations into the micro-and nanostructure of the anodic oxide film of a titanium implant. The anodic oxidized layer of a Ti6Al4V alloy implant was examined ultrastructurally by transmission electron microscopy (TEM) and scanning electron microscopy (SEM). They were also analyzed using energy dispersive X-ray spectrometry (EDS) and X-ray photoelectron spectroscopy (XPS). The TEM revealed that the oxide layer of the Ti6Al4V implant prepared through anodic oxidation was separated into two layers. Al and V were not present on the top surface of the anodic oxide. This can be attributed to the biocompatibility of the anodic oxidized Ti6Al4V alloy implant, because the release of harmful metal ions such as Al and V can be suppressed by the biocompatibility.
