In this study, the effect of graphene nano-particle content on the mechanical and wear and behavior Zn-Al alloy-based hybrid nanocomposites (HNCs) was investigated. Graphene nanoparticle in different volume percentage ranging from 0–2 (0, 0.5, 1, 2) vol% and B4C nanoparticle in keeping constant at 1 vol% were used for reinforcing materials. ZnAl40Cu2 based HNC powders were produced using mechanical milling method to obtain close homogenous distribution of the reinforcement particles in ZnAl40Cu2 matrix followed by hot pressing technique. High energy ball milling process was carried out at the durations of 8 h. Scanning Electron Microscope (SEM) and Energy Dispersive Spectrum (EDS) was used for microstructural evolution. Ball on disc wear tests were used to determine wear behavior. The results of the ball-on disc wear tests showed that the wear rate of nanocomposites decreased with an increase in the graphene nanoparticle content. At the same time, the hardness and tensile strength of hybrid nanocomposites increased with increasing graphene nanoparticle content. It can be said that graphene has positively effect on the mechanical and wear properties of ZnAl40Cu2 based hybrid nanocomposites.
