The Mg–Al layered double hydroxide (LDH) conversion coatings were first synthesized in situ to modify the AZ91D alloy through urea hydrolysis to adjust the pH values (9.4, 10.4, 11.2 and 11.4). The pH 11.2 Mg–Al LDH possessed the best compactness and good crystallinity compared to other in situ LDH coatings and obtained the lowest corrosion current density (icorr) of (2.884 × 10−6 ± 0.345 × 10−6) A·cm−2, which was attributed to the anion-exchange reaction of LDH and the physical barrier against corrosion owing to the twisted penetration pathway of the interlaced LDH sheets. Core–shell structured Zn–Al LDH@ZIF-8 powder modified with stearic acid (SA) was further wrapped with polyvinylidene fluoride (PVDF) to prepare a hydrophobic double-layered coating on the underlying pH 11.2 Mg–Al LDH (SLLZ). The water contact angle (CA) of the SLLZ coating reached 105.6°, and its icorr decreased to (3.524 × 10−7 ± 0.214 × 10−7) A·cm−2 compared with a single pH 11.2 fil
