文摘

In this research reduced graphene oxide (rGO) was synthesized by reduction of graphene oxide (GO) with N,N diethylhydroxylamine as a reductant. The GO and RGO was characterized by X-ray diffraction (XRD), Fourier transform infrared spectroscopy and atomic force microscopy. Results showed GO was reduced to few-layers level with poor dispersion in water. The composite coating of Ni–Zn–rGO and Zn–Ni–GO on copper plate was obtained by the electrodeposition technique. The composite films were studied by XRD and SEM. The composites coating was subjected to various electrochemical tests such as The electrochemical impedance spectroscopy, taffel plot and Vickers micro hardness to know theirs corrosion behavior and compared with Ni–Zn coating. The results confirmed the addition GO and rGO enrichment corrosion resistance property very much compare to Zn–Ni alloy.
