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