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

Suggestions on
Preparation and
A small test is performed at the end of lecture, so refer to an exercise of a textbook. Check a notebook again and be sure to review. 
Grading Method A mid-term examination (40%), a term-end examination (40%), practice problems (10%) and reports (10%)
More than 60 points is passed. 
Practical Experience Experienced  
Summary of Practical Experience and Class Contents based on it A faculty member with experience working at a major chemical fiber company will explain the corrosion and the protection of chemical plants. 
Message English text will be used.
