The demand for corrosion-resistant coatings, exploration of novel materials and techniques to enhance protective layers' performance. Electrodeposition of metal-nanoparticle composites offers a promising solution to meet these requirements. Among these composites, nickelmolybdenum (Ni-Mo) coatings have shown increase in corrosion enhansment and mechanical properties. This study focuses on optimizing the electrodeposition parameters to fabricate Ni- Mo improved corrosion resistance composite coatings and surface morphology. To get good coating characteristics, a nickel bath solution with varying concentrations of nanosized molybdenum particles was prepared. The composition of critical parameters was carefully investigated. Additionally, sodium dodecyl sulfate (SDS) as a surfactant was studied to understand its different characteristics on the coating's surface features. Characterization techniques, ie, scanning electron microscopy (SEM) and energy-dispersive X-ray spectroscopy (EDX), were employed to analyze the surface morphology and elemental mixture of the coatings. Tafel extrapolation and impedance spectroscopy were used to verify electrochemical corrosion behaviour. To evaluate the coatings' corrosion resistance
