| Abstract: | High strength-to-weight ratio aluminium alloy (AA) 2024-T3 is an indispensable material in many transport industries like aerospace as it increases loading capacity and reduces energy consumption1 . Although nano-to-micro scale intermetallic particles (IMPs) are the main contributors to mechanical properties, they are also the main culprits for the most insidious site-specific local degradation events at the surface of AA20242 . IMPs such as Al2CuMg and Al2Cu tend to dealloy at the open circuit potential (OCP), leading to the creation of catalytic high surface area copper enriched intermetallic remnants and associated copper redistribution (i.e., copper replating) on the alloy surface3–8 . Both of these processes significantly support increased oxygen reduction reaction (ORR) rates leading to increased local alkalinity due to the production of OH− ions, causing aluminium matrix dissolution in the form of localised trenching around the IMPs and pit initiation and growth9–11. Therefore, an effective way to increase the corrosion resistance of AA2024 is to suppress the dissolution of IMPs. One aspect of current research in corrosion inhibition has focused on organic molecules with heteroatoms, such as nitrogen, oxygen, sulphur and phosphorus, that contain a lone pair of electrons and/ or delocalised π electrons due to the presence of multiple bonds or aromatic rings12. |
