Course description and aims

In this class, students learn surface structure of metals, thermodynamics of electrochemistry, kinetics of electrochemistry and corrosion phenomena of metals.
Electrochemistry is very important for understanding metallic corrosion, electrolytic process, battery and fuel cell etc. This course will allow them to understand fundamental electrochemistry and corrosion phenomena.

Student learning outcomes

By completing this course, student will be able to understand fundamental electrochemistry and mechanism of metallic corrosion.


Electrochemistry, Corrosion

Competencies that will be developed

Specialist skills Intercultural skills Communication skills Critical thinking skills Practical and/or problem-solving skills

Class flow

To allow students to get a good understanding of the course contents, related exercise problems are provided in every class.

Out-of-Class Study Time (Preparation and Review)

To enhance effective learning, students are encouraged to spend approximately 100 minutes preparing for class and another 100 minutes reviewing class content afterwards (including assignments) for each class.
They should do so by referring to textbooks and other course material.


No textbook is set.

Reference books, course materials, etc.

Course materials are provided during class.
