Abstract

In this work, acetoxime, zinc chloride, and acetoxime adduct of zinc chloride, ZnCl2·2{HON=C(CH3)2} (ZA) were investigated as corrosion inhibitors in 3.5% NaCl solution on mild steel. The electrochemical analysis was performed using polarization measurements and electrochemical impedance technique and surface analysis was done by scanning electron microscope (SEM) 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 the solution phase. SEM methods were used to examine the sample�s surface in the presence of inhibited solutions. The efficiency of inhibition increased with the increasing concentration and attained the values of 97.18% for the 3 mM concentration of ZA. © 2024 AMPP.
