Thermodynamics and electrochemistry are the basis of the course and important concepts such as local cell model for corrosion, charge transfer process, and heterogeneous reaction mechanics are reviewed. On the basis of the knowledge of corrosion phenomena, the methods are introduced how one can protect metals and alloys against corrosion. 到達目標 Course Goals To gain an ability to consider and design the corrosion protection for the metals and alloys. 授業計画 Course Schedule Outline: 1.
