Abstract: Graphene-based, molybdenum oxide-based and composite coating were prepared by one-step electro-deposition without using aggressive solutions. The coatings were characterised by Scanning Electron Microscope (SEM). The corrosion resistance of the three coatings were evaluated by immersion test (ASTM G31-72), salt spray test (ASTM B117-16) and potentiodynamicpolarisation, in 5% NaCl and 2% H2SO4 respectively. All of the results indicated that reduced graphene oxide – molybdenum oxide (rGO/MoO) composite coating exhibits the highest corrosion resistance in both saline and acidic environment. This could be ascribed to the synergistic effect of both graphene and molybdenum oxide with the combination of high mechanical strength and superior chemical resistance.
Keywords: The Coatings were Characterised by Scanning Electron Microscope.
