Abstract
In this study the effect of electroplating bath temperature on the behavior of nickel-Graphene composite coating and also on the morphology and corrosion properties were investigated. For this reason nickel sulfamate additive free bath with grapheme were used. Electroplating process was carried out with DC generator and at three temperatures (35, 45, 55 °C ). surface morphology and crystallographic texture of electroplating nickel- grapheme were investigated with Field Emission Scanning Electron Microscope(FESEM).Corrosion behavior of nickel-Graphene coating were investigated with potential dynamic polarization test results.Results shown that to increases intemperature also will cause increases in Graphene Nano particles absorptionbut up to 50 °C the absorption of graphene reduce. Also increases in temperature will cause Graphene Nano particles agglomerated and lack of uniformity in the coating. As a result the corrosion resistance of the coating is reduced.
