Measurements in corrosion using Pourbaix diagrams is a free online course that begins by introducing you to the construction of the Pourbaix diagram for a Ni-H2O system, as well as happens when the pH concentration of the H+ ion increases. The course will also introduce you to the process for identifying where acidic reactions, as well as basic reactions will happen during the corrosion process. The schematic phase diagram for aluminium will also be covered in this course.
This course then explains the steps used in the estimation of corrosion rate, as well as the concept of kinetics or rate of corrosion. You will learn about the importance of determining the rate of dissolution of metal for any given reaction, as well as how the rate of dissolution is measured. This course will teach you about the steps for calculating the corrosion rate in the form of mass loss per area per unit time.
Furthermore, this course will help you get familiar with the steps for analysing the Pourbaix diagram for a corrosion reaction. You will learn about the different stability phases for a given corrosion reaction, as well as how these phases are relevant. This free online course will be of great interest to students, researchers, and anyone with an interest in using Pourbaix diagrams to measure corrosion. So, register for this course and start your next learning journey today.Start Course Now
