Abstract

The invention discloses an RE-Ni-Mo/GO nano composite deposition liquid. Each liter of the deposition liquid comprises 0.25-5g of graphene oxide, 45-55g of nickel sulfate, 4-10g of sodium molybdate, 55-65g of trisodium citrate, 0.2g of lauryl sodium sulfate, 0.1-5g of a rare earth element RE and the balance of distilled water. The invention further discloses a method for forming an RE-Ni-Mo/GO multifunctional nano composite deposition layer on the surface of low-carbon steel. By adopting the composite deposition liquid and with the combination of ultrasonic wave and electric deposition techniques, the RE-Ni-Mo/GO multifunctional nano composite deposition layer can be prepared on the surface of low-carbon steel. By adopting the composite deposition layer prepared by using the method disclosed by the invention, the corrosion resistance, the surface hardness, the wearing resistance, the breaking strength and the like of the low-carbon steel are effectively improved, and moreover, the difficulty that powder micro particles can be agglomerated in conventional composite electric deposition.

Description
