Metal enhancement is crucial for reducing energy use and material waste. Composite electrodeposition is an economic and efficient method for improving the surface properties of metals. Herein, Ni-W matrix composite coatings reinforced with graphene nanoplatelets (GNPs) are prepared on 7075 aluminum (Al) alloy plates by the co-deposition technique. Characterization results reveal that the mechanical properties and corrosion resistance of the coating can be improved by the successful embedding of GNPs. The Ni-W/GNP coating exhibits rougher, cauliflower-like morphology, higher microhardness (782.6 HV), lower wear rate (2.72 x 10(-5) mm(3) N-1 m(-1)), and better corrosion current density (18.19 mu A cm(-2)) compared with the Ni-W coating (578.2 HV, 7.43 x 10(-5) mm(3) N-1 m(-1), and 25.16 mu A cm(-2), respectively). Moreover, X-ray diffraction (XRD) spectroscopy and analysis verify that the grain size is decreased for GNP-reinforced composite coatings with a typical Ni-based solid-solution phase.
