Effect of physical barrier and anion-exchange process of nitrate-intercalated ZnAl layered double hydroxide films grown on Al on corrosion protection

ZnAl layered double hydroxide (ZnAl-LDH) film loaded with nitrates was prepared on the surface of pure Al plate by hydrothermal reaction. The anion-exchange process of ZnAl-LDH in corrosive NaCl solution was demonstrated by the X-ray Diffraction (XRD). The corrosion protection behavior of this fabri...
