Synthesis of Ni-GO nanocomposite coatings: Corrosion evaluation
Source abstract
Abstract
Abstract In this investigation, surface morphology and corrosion behavior of Nickel-Graphene Oxide (Ni-GO) nanocomposite coating were investigated which is applied by electroplating method on pure commercial titanium plates as substrate. Watt`s bath containing different weight percentages of the GO, 0, 1, 5, and 10 weight percent was used to determine the optimum weight percent of GO. The achieved surface morphologies were observed by both Field Emission Scanning Electron Microscopy (FE-SEM) and Atomic Force Microscopy (AFM). The results showed the successful deposition of Ni-GO nanocomposite coating on the substrate. The addition of GO in an electrolytic bath causes increases micro-hardness of the surface from 205 HV of pure commercial titanium up to 473.1 HV at the sample with 10 wt% of GO. Corrosion performance of the synthesized layers was studied by Polarization and Electrochemical Impedance Spectroscopy Curves and the effect of addition GO was investigated. Based on the obtained results and as a result of the uniformity of coatings, the corrosion resistance of nanocomposite coating with 10 wt% of GO was enhanced remarkably in comparison to the pure nickel coat.
