“…The annealed Ti‐6Al‐4V 900 had peaks at 233, 443, 609 — , and 793 cm −1 as shown in Figure 3A which shows the presence of rutile 68 . This result is typical of Ti‐6Al‐4V annealed surfaces at temperatures above 780°C as reported in prior work 69–71 . The formation of TiO 2 after the heat treatment at 900°C facilitates the deposition of HA onto the Ti‐6Al‐4V and enhances biointegration.…”

Despite the attractive combinations of cell/surface interactions, biocompatibility, and good mechanical properties of Ti‐6Al‐4V, there is still a need to enhance the early stages of cell/surface integration that are associated with the implantation of biomedical devices into the human body. This paper presents a novel, easy and reproducible method of nanoscale and nanostructured hydroxyapatite (HA) coatings on Ti‐6Al‐4V. The resulting nanoscale coatings/nanostructures are characterized using a combination of Raman spectroscopy, scanning electron microscopy equipped with energy dispersive x‐ray spectroscopy. The nanostructured/nanoscale coatings are shown to enhance the early stages of cell spreading and integration of bone cells (hFOB cells) on Ti‐6Al‐4V surfaces. The improvements include the acceleration of extra‐cellular matrix, cell spreading and proliferation by nanoscale HA structures on the coated surfaces. The implications of the results are discussed for the development of HA nanostructures for the improved osseointegration of Ti‐6Al‐4V in orthopedic and dental applications.

“…Sodium titanate, depending on its stoichiometry, showed wide peaks at 285cm -1 and at 740 cm -1 [16]. Rutile had peaks at 220, 450, 610, and 800 cm -1 and anatase at 142 and 200 cm -1 [17,18]. The Raman technique has been used to differentiate the amorphous phases of crystalline formed in processes of oxidation of metals, specifically in titanium and its alloys.…”

The Ti6Al4V presented a natural oxide layer that increased the corrosion resistance of the material but decreased the physicochemical compatibility with the bone tissue. The use of polymeric coatings on Ti6Al4V allows the creation of an interface that promotes osseointegration and antibacterial activity. The objective of this work was to analyze a coating on Ti6Al4V obtained by dip-coating with a mixture of chitosan, polycaprolactone, and silver. The synergy between chitosan and silver allows the polymeric matrix to be retained and to enhance the coating's mechanical-structural functions, integrating bone cells and serving as antibacterial agents. Coating morphology was assessed by scanning electron microscopy (SEM) and the distribution of chemical elements was determined by energy dispersive spectroscopy (EDS). Confocal Raman spectroscopy was used to evaluate the composition and structure of the coating. Electrical potential distribution, phase distribution and surface topography of surfaces were analyzed using an electrostatic force microscopy. Contact angle measurements were also performed to determine coating wettability.
