Graphene nano-sheets (GNS) and cationic surfactants (S1&S2) are utilized for nickel composite coatings electrodeposition. They have a significant role in increasing the corrosion resistance of these coatings. A use of Nickel watt’s bath with the addition of GNS as reinforcement material and different surfactants for nano-composite coatings deposition (Ni-GNS) are considered and the outcomes have been examined and discovered. Electrochemical techniques are utilized for examining the corrosion resistance for samples of nano-composite coatings in 0.6 M NaCl. The results suggest that the content of incorporated GNS increases with increasing the extent of GNS in plating bath. All of the Ni-GNS nano-composite layers in presence of surfactant have better corrosion resistance than the nickel coating. The best corrosion resistance value of about 64 kΩ cm2 and relatively highest hardness value of 509 Hv for the composite coating electrode of Ni-GNS/with S1 are in compare with the rest of nano-composite coating electrodes or pure Ni coatings.
