A nickel matrix with silicon carbide nanoparticles composite coating is prepared by electrodeposition on non‐alloyed steel, assisted with an ultrasonic treatment of the galvanic bath. The abrasion and erosion wear resistance of the coating is determined, as well as its micro‐hardness. The structure and the composition of the nickel nanocomposite coating is defined using scanning electron microscopy and energy‐dispersive X‐ray spectroscopy. The corrosion behavior is investigated by the potentiodynamic polarization methods in the 3.5 wt% sodium chloride solution. The results show improved mechanical properties, wear and corrosion resistance as compared to the nickel metallic coating.
