Surface functionalization of anodized tantalum with Mn3O4 nanoparticles for effective corrosion protection in simulated inflammatory condition
نویسندگان
چکیده
The study highlights the corrosion behavior of untreated and treated tantalum with addition trimanganese tetraoxide (Mn3O4) nanoparticles in simulated inflammatory media. anodic layer was produced on pure by anodization electrolytes composed ammonium fluoride, ethylene glycol, water. Nanoparticles were deposited uniformly surface anodized electrophoretic deposition (EPD) method. results revealed that anodic/EPD coating possessed more compact microstructure higher bond strength than coating. Simulated medium based phosphate-buffered saline additions H2O2 HCl. Potentiodynamic polarization electrochemical impedance spectroscopy studies showed Mn3O4 layers protected from corroding an acidic condition. Finally, protection mechanism NPs condition presented.

Facile Surface Functionalization of Hydrophobic Magnetic Nanoparticles
Nonpolar phase synthesized hydrophobic nanocrystals show attractive properties and have demonstrated prominent potential in biomedical applications. However, the preparation of biocompatible nanocrystals is made difficult by the presence of hydrophobic surfactant stabilizer on their surfaces. To address this limitation, we have developed a facile, high efficiency, single-phase and low-cost meth...

We present a systematic methodology to functionalize magnetic nanoparticles through surface-initiated atom-transfer radical polymerization (ATRP). The magnetite nanoparticles are prepared according to the method proposed by Sun et al. (2004), which leads to a monodisperse population of ~ 6 nm particles stabilized by oleic acid. The functionalization of the nanoparticles has been performed by tr...

Corrosion is the degradation or deterioration of metal components due to a reaction with the environment. Chromate conversion coating is applied to passivate metallic surface to slow down (and prevent to some extent) corrosion process. Chromate conversion process uses chromium compounds including hexavalent chromium, which is toxic, carcinogenic and hazardous to human health and environment. He...
