Nano-wear, nano-hardness and corrosion-resistance of electroplated nickel surfaces after co-implantation of Cr+ and N2+ ions

► Novel sequential co-implantation of Cr+ and N2+ ions on electroplated nickel. ► Roughness and hardness characterization of Cr+ and N2+ co-implanted nickel surfaces. ► Enhancement of wear and corrosion protection of micro-embossing tool surfaces.
