Abstract
The corrosion problem is a great importance, which faced the world from the last years until now, we can’t hide this problem from our live but we can reduce it in the metals by several methods as the environmental need. This work discusses the corrosion of copper in 1 M HNO3. This work consists of three basic chapters. Chapter one: this chapter discusses corrosion theory, causes of corrosion, forms of corrosion, corrosion migration, Types of inhibitors, literature survey of corrosion of copper and aim of this study. Chapter two: it includes the chemicals composition of the investigated material, preparation of the used HNO3 solution, the used organic compounds, solutions and procedures used for the corrosion measurements such as a weight loss and electrochemical techniques. Chapter three: it deals with the results obtained and their discussion and this chapter is divided into three sections. Conclusion: the weight loss, potentiodynamic polarization, electrochemical impedance spectroscopy (EIS) measurements, electrochemical frequency (EFM) and quantum calculations supports the assumption that corrosion inhibition primarily takes place through adsorption of the inhibitors on copper surface. agreement among these different independent techniques indicates the validity of the obtained results.
