Diploma in Electrochemistry of Corrosion
The free online course on the electrochemical nature of corrosion, as well as the thermodynamics aspect of corrosion.
Description
Electrochemistry of corrosion is a free online course that begins by introducing you to the various processes that can cause corrosion, as well as the impact of different forms of corrosion. The course will also introduce you to the electrochemical nature of corrosion, as well as aspects that show the thermodynamics of corrosion. The relationship between free energy and the equilibrium constant, as well as how the Nernst equation can be derived for a reaction will also be covered in this course.
This course then explains the various limitations of standard reduction potential series, as well as how the Pourbaix diagram is constructed. You will learn about the positions where the acidic reactions and basic reactions will happen, as well as the schematic phase diagram for aluminium. This course will teach you about the steps used in the estimation of corrosion rate, as well as kinetics or rate of corrosion for a metal.
Furthermore, this course will help you get familiar with the electrode double layer concepts, as well as the different types of polarization and the correlation between current density and overvoltage. You will learn about the forms of polarization, as well as the steps in deriving the mixed potential theory. This free online course will be of great interest to students, researchers, and anyone with an interest in the process of corrosion and its effects on the environment. So, register for this course and start your next learning journey today.
