Abstract The corrosion problem is a great problem, which faced the world from the last years until now. This work discusses the corrosion of α-brass in 1 M HNO3. The aim of this work contains three main chapters. The first chapter: Deals with the Introduction, which includes corrosion theories, types of corrosion, corrosion protection, literature survey on corrosion behavior of α-brass in aqueous solutions and the aim of this study. The second chapter: It includes the experimental techniques, preparation of the used solutions, includes the chemical composition of the investigated compounds, the instruments and the procedures used The third chapter: Deals with the results obtained and their discussion. The electrochemical measurements and quantum calculations support the assumption that corrosion inhibition primarily takes place through adsorption of the inhibitors on brass surface. Agreement among these different independent techniques indicates the validity of the obtained results. This thesis contains also references, Arabic and English summaries. |
