Electroplating composite coating is an effective method to prepare composite coating through the codeposition of metallic, nonmetallic, or polymer particles with metal to improve properties such as corrosion resistance, hardness, and wear performance. This paper reports the synthesis of a novelNi-BaFe12O19 magnetic nanocomposite coating exhibiting improved corrosion resistance. In the present paper, BaFe12O19 particles were synthesized by a single-step solution combustion method and characterized for phase, particle size, and morphology. These particles were incorporated in a nickel metal matrix, and the properties of the coatings like nanohardness and corrosion resistance were investigated.The coating microstructure was also studied using field emission scanning electron microscope. A Vickers hardness of 7 77HV was exhibited by Ni-BaFe12O19, and plain Ni coating exhibited a hardness of 517HV. The Ni-BaFe12O19 composite coating exhibited improved corrosion resistance compared to plain Ni coating.
