Electropolymerized Coatings of Poly (o-anisidine) and Poly (o-anisidine)-TiO2 Nanocompsite on Aluminum Alloy 3004 by using the Galvanostatic Method and Their Corrosion Protection Performance

摘要

Poly (o-anisidine) (POA) and also poly (o-anisidine)-TiO2 (POA-TiO2) nanocomposite coatings on aluminumudalloy 3004 (AA3004) have been investigated by using the galvanostatic method. The electrosynthesizedudcoatings were characterized by FT-IR, SEM- EDX, SEM and AFM. The corrosion protection performancesudof POA and also POA-TiO2 nanocomposite coatings were investigated in 3.5% NaCl solution by usingudthe potentiodynamic polarization technique and electrochemical impedance spectroscopy (EIS). Theudcorrosion rate of nanocomposite coatings was found ∼900 times lower than bare AA3004. The results ofudthis study clearly ascertain that the POA-TiO2 nanocomposite has outstanding potential to protect theudAA3004 against corrosion.When you are citing the document, use the following link http://essuir.sumdu.edu.ua/handle/123456789/34811
