Abstract
The study highlights the corrosion behavior of untreated and treated tantalum with addition of trimanganese tetraoxide (Mn3O4) nanoparticles in simulated inflammatory media. The anodic layer was produced on pure tantalum by anodization in electrolytes composed of ammonium fluoride, ethylene glycol, and water. Nanoparticles were deposited uniformly on the surface of the anodized tantalum with the electrophoretic deposition (EPD) method. The results revealed that the anodic/EPD coating possessed more compact microstructure and higher bond strength than the anodic coating. Simulated inflammatory medium was based on phosphate-buffered saline with additions of H2O2 and HCl. Potentiodynamic polarization and electrochemical impedance spectroscopy studies showed that the anodic and Mn3O4 layers protected the tantalum from corroding in an acidic inflammatory condition. Finally, the corrosion protection mechanism of Mn3O4 NPs in inflammatory condition was presented.Description
| openaire: EC/H2020/860462/EU//PREMUROSA This study has received funding from the European Union's Horizon 2020 Research and Innovation Program under grant agreement no. 860462 for “PREMUROSA” project (A.B–K., M.G.). The fabrication of the anodic and EPD coatings was performed at Materials and Energy Research Center, Tehran, Iran. The authors are willing to express their gratitude for this support.
