Abstract The corrosion problem is a great problem, which faced the world from the last years until now, we can’t hide this problem from our live but we can reduce “inhibit” it in the metals by several methods as the environment need. This work discusses the corrosion of C-steel in 2M HCl. This work contains three basic chapters Chapter one: “INTRODUCTION“ This chapter discusses: corrosion theory, causes of corrosion, forms of corrosion, corrosion migration, types of inhibitors, literature survey of C-steel corrosion and aim of this study Chapter two: ” EXPERIMENTAL AND TECHNIQUES” It includes the chemical composition of the investigated material, preparation of the used hydrochloric acid solution, the used organic compounds, solutions and procedures used for the corrosion measurements such as a weight loss and electrochemical techniques. Chapter three: ”RESULTS AND DISCUSSION” It deals with the results obtained and their discussion and this chapter is divided into six sections In conclusion : The weight loss, polarization, potentiodynamic polarization, electrochemical impedance spectroscopy (EIS) measurements, electrochemical frequency modulation method (EFM) and SEM analysis support the assumption that corrosion inhibition primarily takes place through adsorption of the inhibitors on the C-steel surface. Agreement among these different independent techniques indicates the validity of the obtained results. |
