Abstract

The inhibition action of natural honey was investigated with two concentrations by using weight loss method, potentiodynamic polarization technique and electrochemical impedance spectroscopy techniques. 75g and 150g of honey of were diluted in 14 litres of tropical seawater in order to produce two different concentrations. The weight loss of aluminium alloy was increased with respect to time. It was found that at higher concentration (150g), the weight loss is lower compared to 75g of honey with the corrosion inhibition efficiency increases to 76%. Potentiodynamic polarization method indicates that honey which was used as inhibitor is a mixed-type inhibitor with predominantly control of anodic reaction. The presence of honey significantly decreases the values of corrosion current density. Electrochemical impedance spectroscopy shows reduction in double layer capacitance and increase polarization resistance. Inhibition efficiency increases with the increase of concentration.
