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.
