英文摘要Zn-Al layered double hydroxides (LDHs) intercalating with molybdate anions was developed to inhibit the corrosion of mild steel in neutral chloride conditions. The LDH compounds were prepared by a method involving co-precipitation and anion-exchange and characterized by scanning electron microscopy (SEM), X-ray diffraction (XRD) and Fourier transform infrared spectroscopy (FTIR), respectively. The anticorrosion capabilities of the LDHs hybrids were analyzed by using open circuit potential (OCP), electrochemical impedance spectroscopy (EIS) and potentiodynamic polarization curve. A significant reduction of the corrosion rate is observed in the presence of a 2 g/L concentration of the LDHs hybrids in the corrosive media. The mechanism is that the intercalated molybdate anion can slowly diffuse out of the inner structure of LDHs in a controllable way and result in a relatively long-term effect of corrosion inhibition. The result presented here underlines the great potential of the controlled release mechanism for marine anticorrosion applications.
