Abstract
The influence of date palm (Phoenix dactylifera L.) (PDL)
fruit juice on 7075 type aluminum (AA7075) alloy in 3.5% NaCl solution was
investigated by Tafel extrapolarization and electrochemical impedance
spectroscopy. It was found that PDL fruit juice acted as a slightly cathodic
inhibitor, and inhibition efficiencies increased with the increase of PDL fruit
juice concentration. The adsorption of the inhibitor on the metal surface was
found to obey the Temkin adsorption isotherm and has a physisorption mechanism.
