Many different types of destructive attack can occur to marine structures, ships and other equipments used in sea water service. Year upon year the cost of marine corrosion has increased until it is estimated today at 4% of the Gross National Product. Aluminium alloys are important materials and commonly used in marine applications. In this aluminum 2024 were subjected to seawater. Sodium Benzoate was used as corrosion inhibitors for aluminium alloy in aggressive marine environment. In order to study the corrosion behavior of aluminum alloy AA2024 in seawater, the electrochemical behavior of aluminum alloy was investigated with different inhibitor concentrations, potentiodynamic polarization and electrochemical spectroscopy (EIS). The morphology study was carried out to observe the development of thin film on the specimen and this study was performed using Scanning Electron Microscopy (SEM). EIS data showed that the mechanism of corrosion depends on inhibitor concentration.
