Abstract
In this study, ZnAl layered double hydroxide (LDH) nanocontainers were grown in situ on AA2024 aluminum alloy through a controlled hydrothermal process, using the native oxide layer as an internal aluminum source, and succinic acid (SA) and tartaric acid (TA) inhibitor anions were subsequently intercalated into the LDH interlayers via an optimized ion-exchange treatment performed at 60 °C under ambient pressure, with exposure times from 15 min to 5 h to evaluate the effect of intercalation duration on inhibitor uptake and film stability. Structural and morphological analyses by X-ray diffraction (XRD) and scanning electron microscopy (SEM) confirmed the formation of well-crystallized LDH films and the…
