授業の目標 Objectives: The aim of this course is to provide basic knowledge of corrosion and corrosion protection of metals and alloys from electrochemistry. 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.
