Compact and uniform NiW composite coatings filled with ceramic particles such as CeO 2 were electrodeposited on brass substrates using direct current (DC) and a well–designed pulse reverse current waveforms (PRC). PRC coatings exhibited the noblest corrosion potential and lowest current density compared to DC–electrodeposited coatings. Among all PRC coatings, PRC–NiW–CeO 2 demonstrated the highest corrosion potential (−4.72 × 10 −1 V) and the lowest current density (5.32 × 10 −6 V). It also seems that the addition of CeO 2 particles to the NiW matrix enhanced the wear resistance of the coatings, and the lowest wear volume of (133.10 × 10 3 µm 3 ) and friction coefficient of 0.25 were obtained due to the formation of the uniform, void free and compact structures with a high content of CeO 2 particles in the coating.
