20.500.12556/DiRROS-22129 Inhibition of the localised corrosion of AA2024 in chloride solution by 2-mercaptobenzimidazole and octylphosphonic acid 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. aluminij nanomateriali redukcije kisika reakcije baker true false true Springer Nature Švica Angleški jezik Slovenski jezik © The Author(s) 2023 Neznano 2025-04-29 11:15:14 2025-04-29 11:15:14 2025-10-24 03:50:35 0000-00-00 00:00:00 2023 0 0 Nasl. z nasl. zaslona; Opis vira z dne 11. 7. 2023; str. 1-10 55 2023 0000-00-00 Zaloznikova Objavljeno NiDoloceno 2023-01-22 2023-05-23 2023-07-04 54 2397-2106 10.1038/s41529-023-00368-z 158516483 RAZ_Kozlica_Dzevad_2023.pdf RAZ_Kozlica_Dzevad_2023.pdf 1 FCB3562C3DA5A4A6FA0E281F9B45FC99 aa3b4adb24c412ddc890a15dc81a8188c881e0898ddb2c5e120ac9b858431776 76f20d7c-24db-11f0-963a-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=32005 Institut Jožef Stefan 0 0 0
