A Study on the Effect of Lawsone as Complexing Agent in the Electroless Zn-P Deposition

The effect of Lawsonia inermis Linn Leaf extract on electroless deposition Zinc-P alloy mild steel is studied in alkaline solutions. experimental processing parameters the rate investigated during plating. bath compositions and operating conditions are optimized. results obtained show inclusion Zn-P coating found to be increased by increasing volume additives from 0.5ml 1.5ml. Structured UV - A significant spectroscopic absorption taken ensure presence Lawsone binary complex bath. In absence a complexing agent, additive develops more features levels arrangement. It offers idea changing sodium citrate with Lawsone. as agent tested SEM, EDAX, AFM, XRD corrosion studies. efficiency assessed polarization electrochemical impedance spectroscopy.
