Description

Mixed potential theory in corrosion is a free online course that begins by introducing you to the concept of the electrode double layer in a reaction, as well as the significance of the inner Helmholtz plane and outer Helmholtz plane. The course will also introduce you to the different types of polarization, as well as the correlation between current density and overvoltage. The derivation of the Butler-Volmer equation, as well as how the Tafel equation is derived will also be covered in this course.

This course then explains the concepts of activation polarization and concentration polarization, as well as total polarization in corrosion. You will learn about the derivation of the mixed potential theory, as well as some case studies that highlight the mixed potential theory and the events of corrosion. This course will teach you about how the Tafel plot can be explained using activation polarization.

Furthermore, this course will help you get familiar with the step-by-step process for drawing the Evans diagram for a reaction. You will also learn about the different changes that occur in the corrosion rate of a reaction. This free online course will be of great interest to students, researchers, and anyone with an interest in mixed potential theory and how it relates to corrosion. So, register for this course and start your next learning journey today.
