Abstract
Mg-Al based layered double hydroxide (LDH) coating intercalated with 8-hydroxyquinoline (8HQ) was successfully prepared on AZ31. The influence of concentrations of 8HQ on the morphology and corrosion resistance is reported first time. X-ray diffraction (XRD) and Fourier transform infrared (FTIR) spectra confirm the intercalation of 8HQ. Furthermore, scanning electron microscopy (SEM) reveals concentration dependence of morphology of LDH. The enhancement in corrosion resistance is a function of morphological change, adsorption of 8HQ and chelation with Mg2+. The optimum amount of 8HQ enhances corrosion resistance of LDH coating. The deductions of this study deliver valuable understandings of corrosion protection mechanism of Mg-Al-LDH coatings.
