The
main objective of this work has been the deposition of Nickel (Ni)–Graphene
nanoplatelets (GNPs) composite coatings onto Ti-6Al-4V alloy plates via a pulse
electrodeposition technique from a Watt’s type bath. The characterization of
the coatings was done by structural surveys, hardness measurements and wear
tests. In this current work, XRD and SEM analysis demonstrated the better
grained and compact property of the Ni-GNPs deposits. The surface roughness of
the composite coatings was significantly decreased with the addition of GNPs. Furthermore,
the incorporation of GNPs into the Ni matrix improved both hardness and wear
behaviour of the composite coating compared to the pure Ni coating.
