“…The anodized titanium possess higher surface energy and wettability compared to as receivedtitanium 25 . Furthermore, it has been suggested that titania with a 3-D nanoporous structure may enhance hydroxyapatite formation when compared to dense titania 26 . Osteoblast adhesion and activity is enhanced on rougher titanium surfaces than on the smoother surfaces.…”

In this study, the effects of the parameters such as applied potential difference, time and annealing temperature in the titania nanotubes formation were evaluated. The morphology of the nanotubes was evaluted by using Field Emission Gun -Scanning Electron Microscope (FEG-SEM), Atomic Force Microscope (AFM), contact angle and X-rays diffraction (XRD). Self-organized nano-structures were formed on the Ti-7.5Mo alloy surface from the same electrolyte (glycerol/NH4F) for all conditions. It was observed that the potential influenced the diameter while the length was changed according to the anodization time lenght. The presence of the phases anatase and rutile was altered by annealing temperature. Results showed that 20V-48h-450 ºC was the better than other conditions for application as biomaterial.

“…The native TiO 2 layer, which is approximately 2-5 nm thick, at the metal or alloy surface is defined as bioinert, and cannot easily bind to the bone tissue. Only thicker and more stable TiO 2 based oxide layers were shown to be favourable for the surface bioactivity [7,8].…”

In this work, we report for the first time on the use of melt spun glass-forming alloysTi 75 Zr 10 Si 15 (TZS) and Ti 60 Zr 10 Si 15 Nb 15 (TZSN) -as substrates for the growth of anodic oxide nanotube layers. Upon their anodization in ethylene glycol based electrolytes, highly ordered nanotube layers were achieved. In comparison to TiO 2 nanotube layers grown on Ti foils, under the same conditions for reference, smaller diameter nanotubes (~116 nm for TZS and ~90 nm for TZSN) and shorter nanotubes (~11.5 µm and ~6.5 µm for TZS and TZSN, respectively) were obtained for both amorphous alloys. Furthermore, TEM and STEM studies, coupled with EDX analysis, revealed a double-wall structure of the as-grown amorphous oxide nanotubes with Ti species being enriched in the inner wall, and Si species in the outer wall, whereby Zr and Nb species were homogeneously distributed.

“…Over the last decade, various methods for producing HA coatings on titanium and its alloys have been developed [10][11][12][13][14][15][16][17][18][19][20][21][22][23][24][25] . These include plasma spray [10][11][12][13][14][15][16][17][18] , sputtering 19,20 , electrophoretic deposition 21,22 , immersion in simulated body fluid (SBF) 23 , biomimetic techniques 24 , sol-gel procedures 25,26 and laser ablation 27 .…”

Mg-Containing Hydroxyapatite Coatings Produced by Plasma Electrolytic Oxidation of Titanium

et al. 2017

Plasma Electrolytic Oxidation (PEO) is promising for the processing of biomaterials because it enables the production of surfaces with adjustable composition and structure. In this work, aimed at the improvement of the bioactivity of titanium, PEO has been used to grow calcium phosphide coatings on titanium substrates. The effects of the addition of magnesium acetate to the electrolytes on the composition of the coatings produced during 120 s on Ti disks using bipolar voltage pulses and solutions of calcium and magnesium acetates and sodium glycerophosphate as electrolytes have been studied. Scanning electron microscopy, X-ray energy dispersive spectroscopy, Rutherford backscattering spectroscopy, X-ray diffractometry with Rietveld refinement and profilometry were used to characterize the modified samples. Coatings composed of nearly 50 % of Mg-doped hydroxyapatite have been produced. In certain conditions up to 4% Mg can be incorporated into the coating without any observable significant structural modifications of the hydroxyapatite.
