摘要: 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 the GO, 0, 1, 5, 10 percent was used to determine optimum GO. The achieved morphologies observed both Field Emission Scanning Electron Microscopy (FE-SEM) Atomic Force (AFM). results showed successful deposition Ni-GO addition GO in an electrolytic causes increases micro-hardness from 205 HV up 473.1 at sample with wt% Corrosion performance synthesized layers studied Polarization Electrochemical Impedance Spectroscopy Curves effect investigated. Based obtained a result uniformity coatings, resistance enhanced remarkably comparison nickel coat.
