Studying the Effects of Extracts that Prevent Corrosion on Sheet Metal in an Acidic Condition

Abstract

The prevention of corrosion in steel materials in acidic conditions is summarized in this paper. There are many accelerated corrosion preventives for acidic solutions available. High temperatures, lowgrade steels, and HCl solutions are the main focus points. The creation of corrosion inhibitor compositions which combine corrosion inhibitors with surfactants, solvents, and expressions to increase the potency of single compounds at extreme temperatures is another focus of this analysis. This review’s knowledge is applicable to a variety of industrial domains, particularly the well acidizing process and other situations when corrosion inhibitors of steel metals are required. Gravimetric methods for measuring weight loss and gasometric methods for measuring hydrogen evolution were used to study the corrosion inhibitor on mild steel in an acidic media while taking into account the thermodynamic and kinetic factors required for corrosion tests performed. The testing results showed that the extract had outstanding inhibitory properties even at higher temperatures. The presence of heteroatoms that can be seen in the FT-IR spectra is thought to be the cause of the maximum level of inhibition efficiency. Its estimated kinetic energy values were all high and improved with the concentration of the extract indicating a larger energy barrier needed to prevent further degradation of the metal. The minimum generated energy indicates a physical adsorption process. The process is a first order reaction according to very linear rate constants.
