Corrosive behaviour of sodium gluconate (SG) with Zn2+ in different metals was studied in potable water. On analysis, in potable water, it was found to be more corrosive towards mild steel in compared to copper. The surface examination studies also carried out with help of Scanning Electron Microscope (SEM), Energy dispersive x-ray analysis (EDX), Atomic Force Microscope (AFM) and Water contact angle technique. The result of water contact angle technique induced by the lotus effect in copper on the surface is superhydrophobic nature and in case of mild steel surface is hydrophobic nature.
