Abstract

In this study, cobalt oxide (Co3O4) and cobalt-doped magnetite (CoFe2O4) nanoparticles were synthesized by a hydrothermal method. They were then used as corrosion inhibitors for corrosion protection of AA2024-T3 aluminum alloys. These obtained nanoparticles were characterized by x-ray diffraction, field-emission scanning electron microscopy, and Zeta potential measurements. Corrosion inhibition activities of Co3O4 and CoFe2O4 nanoparticles were determined by performing electrochemical measurements for bare AA2024-T3 aluminum alloys in 0.05 M NaCl + 0.1 M Na2SO4 solution containing Co3O4 or CoFe2O4 nanoparticles. Corrosion protection for AA2024-T3 aluminum alloys by a water-based epoxy with or without the synthesized Co3O4 or CoFe2O4 nanoparticles was investigated by electrochemical impedance spectroscopy during immersion in 0.1 M NaCl solution. The corrosion protection of epoxy coating deposited on the AA2024-T3 surface was improved by incorporating Co3O4 or CoFe2O4 nanoparticles in the coating. The corrosion protection performance of the epoxy coating containing CoFe2O4 was higher than that of the epoxy coating containing Co3O4.
