<p>The utilisation of graphene-based nanocomposite films for safeguarding the surfaces of steel in engineering is a burgeoning domain, providing substantial improvements in wear and corrosion resistance. This research is attempted to investigate the wear and corrosion behaviour of zinc–molybdenum (ZnMo), zinc–molybdenum with 0.25&#xa0;wt.% graphene (ZnMo0.25G), and zinc–molybdenum with 0.50&#xa0;wt.% graphene (ZnMo0.5G) coatings on mild steel substrates using electro-deposition method with input power in the form of electrical pulses. The pulsed electro-deposition technique utilises an aqueous electrolyte solution of zinc sulphate (ZnSO₄), sodium molybdate (Na₂MoO₄), and citric acid (C₆H₈O₇). The findings indicated that the ZnMo0.5G coating has enhanced wear resistance, owing to the elevated graphene concentration that augmented the load-bearing capacity of the ZnMo matrix. The infusion of graphene into the ZnMo matrix improved grain size control, established dislocation barriers, and diminished material defects. As a result, the ZnMo0.5G coating exhibited a defect-free layered cauliflower surface morphology, leading to enhanced corrosion resistance relative to the ZnMo coating. The increased graphene content also contributes improved resistance to corrosion in ZnMo0.5G in contrast to the pure ZnMo.</p>
