Abstract

The inhibition of corrosion of mild steel in HCl solution by naturally occurring Acacia Senegal has been studied in relation to the concentration of inhibitor and concentration of corrosive medium. It has been observed that the Acacia Senegal alcoholic extract acts as a good corrosion inhibitor in hydrochloric acid solution and the adsorption of the extract provides a good protection against mild steel corrosion.

Highlights

  • Corrosion is the destructive attack on a metal or metal alloy by chemical or electrochemical reaction with its environment[1]

  • It is found that the inhibition efficiency increases with increases of inhibitor concentration for different plant extracts from 0.12%to 0.6% from the mass loss data

  • It was concluded that the plant extracts act as a good inhibitor for mild steel in HCl solution

Summary

Introduction

Corrosion is the destructive attack on a metal or metal alloy by chemical or electrochemical reaction with its environment[1]. The corrosion inhibitor of mild steel in different acid media has been studies by various authors[13,14,15,16]. The test specimens were studies for complete immersion test in different acid solution at 298±1K temperatures with and without inhibitor, after removal of the corrosion product.
