Abstract The aim of this work was to investigate the mechanical properties titanium anodic films (TiO 2 ) produced by oxidation under galvanostatic conditions, using a 1.4 M phosphoric acid electrolyte, with different current densities ( J on commercially pure (cp‐Ti). morphology oxide were observed scanning electron microscopy (SEM), whereas composition film determined Raman spectroscopy. Porosity, average roughness (Ra) and thickness TiO increased applied . Hardness elastic modulus...
The aim of this work was to evaluate the ability a bioactive glass-ceramic induce apatite nucleation on titanium oxide layer produced by micro-arc oxidation. “In vitro” tests were carried out simulated body fluid solution in two different manners: one group soaked SBF, while other together with glass-ceramic. Results revealed that after 7 days, specimens SBF covered an amorphous calcium phosphate layer, plus formed crystalline suggesting thus, provides silanol groups accelerated...
Several papers have reported the grown self-organized nanotube arrays on pure Ti and its alloys to improve surface of these materials for biomedical applications. The growth nanotubes can be influenced by microstructure material; however, few concerning this topic been published. aim work was investigate morphology, cross-section view oxides in relationship Ti-10Nb alloy. alloy obtained anodic oxidation (AO). is composed alfa beta phases that were investigated metallographic analysis,...
There are various surface treatments used to modify titanium surfaces render it bioactive. In this study commercially pure (cp Ti), grade 2 were modified by acid etching (AE) and anodic oxidation (OA) in order evaluate the bioactivity vitro of these using simulated body fluid (SBF). The AE was realized a mixture acids AO 1 mol.L-1 sulfuric acid. films obtained under potentiostatic mode, during 60s as anode bar titanium. All that means cp Ti, analyzed concerning morphology, rugosity,...
Titanium and its alloys are widely used as implants due to their excellent mechanical properties, corrosion resistance biocompatibility. TiO2 nanotubes have been studied surface treatment increase the specific area improve osseointegration. However, thermodynamic stability bioactivity of these nanostructures must be evaluated. The objective this research was obtain oxides on Ti6Al4V alloy analyze electrochemical in physiological solution at 37 °C bioactive response biomaterial. were obtained...
The Ti–Nb alloy binary system has been widely studied with regard to biomedical applications due the high biocompatibility and excellent mechanical properties of alloys. Regarding physical-chemical stability, alloys maintain Ti metal, which is highly resistant corrosion in aggressive media a spontaneous stable oxide layer (TiO2) formed on its surface. objective this study was evaluate resistance Ti–40Nb artificial blood. thermodynamic stability using open circuit potential technique assessed...
