| Abstract: | The present disclosure provides electroplating compositions comprising zinc sulphate, nickel sulphate, nickel chloride, boric acid, and organic additives for depositing zinc-nickel (Zn-Ni) alloy coatings on steel. The disclosure also provides methods for preparing the electroplating compositions and a direct current method for depositing the electroplating compositions on steel substrates. The disclosure further provides steel substrates comprising Zn-Ni alloy coatings. The compositions and methods of the present disclosure provide a higher rate of deposition and coatings with a uniform microstructure and superior corrosion resistance. | ||
