NOVELTY - Preparing silver-graphite-graphene layer comprises (i) processing the surface of the substrate, (ii) pre-plating silver, (iii) silver plating, (iv) composite plating silver-graphite-graphene, and (v) processing the plated surface. USE - The method is useful for preparing silver-graphite-graphene layer. ADVANTAGE - The method improves the wear resistance of traditional coatings, anti-arc burning and corrosion resistance, improves the rate of producing black nano-scale ultrafine particles silver and small amount of silver oxide on the surface of the silver graphene composite coating in the coastal high humidity and high salt spray environment.
