An Electrodeposition Method of Nickel–Graphene Composite Coatings on Ti–6Al–4V alloy

Abstract

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.
