NOVELTY - Surface treatment of zero-valent chromium composite involves preparing graphene oxide chelated metal ion material, carrying out electrochemical co-plating on nickel composite film using copper plated semi-finished workpiece and graphene oxide chelated metal ion material, and carrying out vacuum composite chrome plating on the workpiece. USE - Surface treatment of zero-valent chromium composite. ADVANTAGE - The method is environmentally-friendly, and provides chromium product having excellent corrosion resistance, wiping durability, aging resistance, high and low temperature impact resistance, and improved functionality.
