Thenano composite coatings of Ni-P-GO was obtained on the pre-cleaned aluminum alloy substrate by electroless plating method. Nano graphene oxide (GO) finds extensive applications due to its unique properties.The microstructure and morphology of as plated composite coatings were investigated by EDX, scanning electron microscope andXRD studies.The corrosion behavior of the coatings with and without nano GO was determined in acidic and alkaline medium by potentiodynamic polarization, electrochemical impedance spectroscopy, neutral salt spray and atomic absorption spectroscopy. The composite coatings showed increased corrosion resistance due to the incorporation of nano GO.The microhardness of the coatings was measuredby Vicker‘s hardness method and coating thickness was measured by non-destructive method using 3D optical profilometer.
