the oxygen reduction reaction. 8,9,18 Therefore, in this work, we investigated the effectiveness of Cedbp3 as both an anodic and cathodic inhibitor on intermetallic compounds present as particles in 2024-T3, with the aim of characterizing electrochemically the mechanism of inhibitor action, while adopting a novel approach to achieve this. Ultimately, the inhibitor must reveal mixed properties to approach the inhibition efficiency of chromates. We suggest that Cedbp3 representing an optimized inhibitor of the Ce-based family, based on chemical considerations, will serve as good environmentally benign corrosion inhibitor for AA2024-T3.
