Abstract The synthesis of SiO 2 ‐CaO‐MgO‐P O 5 bioactive glass was carried out by the sol‐gel method. Sol‐gel derived bioglass material crushed into powder to produce pellet disks uniaxial pressing, followed sintering at 900°C. biocompatibility evaluation formed assessed through in vitro cell culture experiments and immersion studies simulated body fluid (SBF) for different time intervals while monitoring pH changes concentration calcium magnesium SBF medium. Scanning electron microscopy,...

Titanium oxides and their alloys are widely used in medical applications because of biocompatibility. However, they characterized by low resistance to corrosion. The HaP + TiO2 nanocomposites’ coating was applied different experiments, especially on a Ti-6Al-4V substrate with the spray pyrolysis process deal such weakness. content effects surface morphology phase composition were investigated using scanning electron microscopy, X-ray microanalysis (SEM-EDXS) diffraction (XRD). mechanical...
Abstract Thermal behavior of electrodeposited hydroxyapatite (HAP) coating on a titanium alloy (Ti6Al4V) is investigated in order to optimize the heat treatment conditions for this prosthetic material. The synthesized coatings are annealed air atmosphere at 400, 600, 800, and 1000 °C, then characterized by X‐ray diffraction (XRD) selected area electron (SAED) structure phases analysis. Scanning transmission microscopy associated energy dispersive microanalysis (SEM‐EDXS STEM) used morphology...
In this paper, 45S5 Bioglass® coatings were elaborated by electrophoretic deposition (EPD) on the titanium alloy Ti6Al4V. An adequate grinding protocol was developed to obtain a stable suspension of submicrometric particles in isopropanol. The voltage and time EPD optimized. optimal 30 V two times (30 90 s) chosen different with thicknesses 21 85 µm, respectively. as-deposited thermally treated following two-step protocol: one hour at 120 °C followed 450 °C. surface morphology chemical...
The aim of this work was to investigate the nanomechanical, adhesion and corrosion resistance hydroxyapatite (HAP) coatings. electrodeposition process used elaborate HAP coatings on Ti6Al4V alloy. effect hydrogen peroxide concentration H2O2 electrolyte heat treatment studied. Surface morphology assessed, before after treatment, by scanning electron microscopy associated with X-ray microanalysis (SEM-EDXS). Moreover, diffraction (XRD) performed identify coatings’ phases composition....
Abstract Calcium phosphate coatings on Ti6Al4V substrates are elaborated by pulsed electrodeposition. The surface morphology and chemical composition of the characterized SEM–EDS. obtained results systematically confirmed at nanometre scale using TEM. Moreover, XRD is performed in order to identify phases. show that electrodeposition allows uniform be without holes craters usually observed with classical After appropriate heat treatment, these have a biphasic stoichiometric hydroxyapatite β...
