Class Objectives /Class Outline	Students can study surface condition of metal, interface between metal and solution, and basic knowledge of electrochemistry to understand corrosion and corrosion protection of metal. Students can acquire electrochemical potential, electrode reaction, polarization, types of corrosion and corrosion protection by this lecture. Corrosion engineering is one of important core technology for safe operation in chemical plants. The evaluation items are as follows. 1) Students can understand surface condition of metal and interface between metal and solution 2) Students can understand types of corrosion, electrode and potential 3) Students can understand Nernst equation and potential-pH diagram 4) Students can understand polarization and Butler-Volmer equation 5) Students can understand Tafel equation, polarization curve, corrosion current and corrosion potential 6) Students can understand passivity and corrosion inhibitors 7) Students can understand coating and corrosion protection
Class Schedule	Lesson 1: Guidance and metal Lesson 2: Corrosion of metal and type of corrosion Lesson 3: Interface between metal and solution and electrical double layer Lesson 4: Electrode and electrochemical potential Lesson 5: Nernst equation Lesson 6: Potential-pH diagram Lesson 7: Polarization and Butler-Volmer equation Lesson 8: Mid-term examination Lesson 9: Tafel equation Lesson 10: Mixed potential and polarization curve Lesson 11: Concentration polarization Lesson 12: Passivity Lesson 13: Corrosion inhibitors Lesson 14: Coatings Lesson 15: Galvanic corrosion and corrosion protection engineering A mid-term and a term-end examination are scheduled.
