Description

This course will introduce you to the important aspects of electrochemical reactions, how they react with the mixed potential theory, as well as the formation of the Helmholtz double-layer and the Tafel equation. You will learn about the area effect on the corrosion of the active component connected to a noble component, as well as galvanic coupling between two active metals in an electrolyte.

You will study the features and elements of passivation, as well as the interaction between polarization and the Pourbaix diagram. Learn about Faraday's two-staged experiment on converting iron with HNO3 (nitric acid) solution from the passive to the active stage, as well as the ennoblement of metal in relation to passivity. The interaction of cathodic and anodic polarization plots when a system goes into passivation mode will also be highlighted in this course.

Furthermore, you will gain an understanding of how to calculate the Pilling-Bedworth ratio in different metals, as well as the two fundamental aspects of oxidation. You will also learn how to plot the Ellingham diagram, as well as how an oxidation process occurs in metal deficient diffusion of the interstitial cation. This free online course will be of great value to anyone with an interest in electrochemical reactions in corrosion – register now and expand your knowledge today.
