description: In this study, the effect of graphene nanoplatelet (GNP) size on the microstructure and hardness of the  electrodeposited nickel–graphene nanocomposite coatings were investigated. GNPs with different sizes  were prepared by using a high energy ball milling technique. The experimental result revealed the high  energy ball milling technique could reduce the size, increase the surface area, and improve the  dispersion ability of GNPs. The microstructure, hardness, and components of the nanocomposite  coatings were greatly affected by GNP sizes. The highest microhardness was measured to be 273 HV for  the nanocomposite coatings containing 5 h-milled GNPs, which is increased up to �47% compared to  pristine Ni coating. The enhancement in the hardness is attributed to the uniform dispersion of the small  GNP sizes inside the Ni matrix and the Ni grain size reduction when using milled GNPs.
