“Exploring the Inhibitory Potential of Acetoxime-Zinc Chloride Adduct in Saline Environments for Mild Steel Corrosion Protection”

Abstract

ABSTRACT In this work, acetoxime, zinc chloride and acetoxime adduct of zinc chloride, [ZnCl2.2{HON=C(CH3)2}] (ZA) were investigated as corrosion inhibitor's in 3.5%NaCl solution on mild steel. The electrochemical analysis was carried out using polarization measurements and electrochemical impedance technique and surface analysis was done by Scanning electron microscope coupled with Energy-dispersive X-ray spectroscopy. Using surface analysis and electrochemical data it was concluded that an inhibition synergy was developed when ZA was taken instead of acetoxime or zinc chloride alone in solution phase. Scanning electron microscope methods were used to examine the samples surface in the presence of inhibited solutions. The efficiency of inhibition increases with the increasing concentration and attained the values of 97.18% for the 3mM concentration of ZA.
