Abstract: The present disclosure provides electroplating compositions comprising zinc sulphate, zinc chloride, boric acid, silicon nanoparticles  and a surfactant and/or grain refiner for depositing zinc-silicon (Zn-Si) composite 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-Si composite coatings. The Zn-Si composite coatings  provided by the compositions and methods of the present disclosure exhibit a higher deposition rate and superior corrosion resistance.
