Corrosion Part II Online Course by Prof. Kallol Mondal | IIT Kanpur

NPTEL is offering online course for undergraduate students in Corrosion Part II.

About the course:

The course will begin with recap of electrochemical polarization and mixed potential theory.
Corrosion events will be discussed on the basis of mixed potential theory. Moreover, passivity and mixed potential theory will also discussed.
The course will also concentrate on different corrosion protection methods, various test methods to understand corrosion and stress effect in combination of corrosion of metals and alloys.
Finally, it will discuss oxidation of metals and alloys.

Course Layout:

Week 1: Introduction: Electrochemical Polarization: Activation and Concentration polarization and Mixed Potential Theory (Recap)
