Abstract

Anti-corrosive properties of natural honey on Al–Mg–Si alloy in seawater were evaluated by potentiodynamic polarization (PP), linear polarization resistance (LPR) and electrochemical impedance spectroscopy (EIS) measurements. All the studied parameters showed good anti-corrosive properties against the corrosion of Al–Mg–Si alloy in the tested solution and their performance increases with corrosion resistant concentration. Polarization data indicated that natural honey is a mixed-type corrosion resistant. LPR and EIS studies showed that there were significant increases in the overall resistance after the addition of natural honey. The adsorption of natural honey on the metal surface obeys Langmuir adsorption isotherm. The analysis of morphology studies confirmed the formation of precipitates of natural honey on the metal surface, which reduced the overall corrosion reaction.
