    Abstract

    The Al-Cu-Mg light alloys storage such that their use for building structural, marine offshore, and aeroplane components with excellent strength/weight ratios would not be possible without adherent anti-corrosion preservation. Many techniques and strategies are still being used to treat the surface, such as cladding, anodizing, and greasing. However, due to the cost, time consumed, and processing these techniques is considered complicated. Therefore, applying volatile organic inhibitors components are now being used effectively. Benzimidazole (BZI) and its derivatives are one of these film-forming chemicals used on copper and steel directly or as injectable combined with other carriers such as fatty acids or dissolvable hydrocarbons with high efficiency on corrosion protection. Therefore, this paper will investigate the enhancement of the corrosion protection afforded by direct spraying of BZI solution on the surface of aluminium alloy 2024-t3. The corrosion protection performance results from the high electro-negativity of BZI and as a film-forming inhibitor, which will be adsorbed on the metallic surface as it may emulate the active protection. The corrosion protection properties of the BZI film-forming coating were preliminary studied within 3.5% NaCl by using electrochemical impedance testing and simulations. The surface chemical adsorption confirmation was done by infrared spectroscopy (ATR-FTIR), supported by analyzing the morphology of the surface before and after the immersion testing by using scanning electron microscopy (SEM) and real-image within one week of immersion. The Benzimidazole film-forming coating exhibited good anti-corrosion properties, providing an adherent protection film on AA 2024-t3 samples comparing to cladded bare AA2024-t3 with a cost-effective and easy applying process.
