Despite the modest amount of Zn, it effectively served as a sacrificial anode to protect the substrate under austenitization conditions. The ±30 °C variation in austenitizing temperature around 900 °C caused structural deformation of the Al-dendrite phase within the coating, which in turn affected the galvanic corrosion rate at the Al-Zn interface. These differences significantly altered the electrochemical behavior and shielding properties of ZnAl-LDH, resulting in variations in the corrosion resistance of the coating. Additionally, when the heat treatment duration was increased by 2 min based on the 5 min heat treatment condition at 900 °C, the corrosion resistance of the AZS coating significantly decreased.
