Introduction to Mixed Potential Theory and Corrosion Processes is a free online course that introduces you to electrochemical polarization and corrosion processes based on the mixed potential theory. It will also introduce you to the Tafel and Butler-Volmer equations, the differences between cathodic and anodic reactions, as well as the connection between activation and concentration polarization to mixed potential theory. The exchange current density in relation to anodic and cathodic polarization will also be covered.
The material then explains the evolution of microstructure of pearlite, its two phases of mixture, formation process, as well as its relationship to cathodic and anodic reactions. You will study the structure of the optical microscope and lamellar structure, as well as the process of etching and basics of galvanic coupling. This course will then teach you about the types of mixed potentials, as well as the equilibrium potentials of ‘E-mix’ and ‘E-mix primer’.
Furthermore, you will get familiar with the relationship between anodic and cathodic reactions on metal, as well as the exchange current density of those reactions on the active component. You will also analyze the depolarizing effect on the hydrogen evolution reaction. This free online course will be of great interest to anyone working with corrosion processes. So, register now and start your next learning journey today.Start Course Now
