摘要：

The properties of graphene coating prepared via dip coating route as an effective anticorrosion barrier on aluminum in 0.5 M NaCl solutions were studied. The Raman spectra analysis indicated that the graphene dip coatings were spread consecutively and uniformly on Al substrates. The potentiodynamic polarization and electrochemical impedance spectroscopy results indicated that the graphene dip coatings were a barrier layer between corrosive medium and Al substrate with a highly protection effective. The corrosion resistance efficiency of the substrate with the coatings was three orders of magnitude higher than that without the coatings. (C) 2014 Elsevier B.V. All rights reserved.
