I am working on determination of corrosion rates using Potentio-Dynamic Polarisation method. I will love to be assisted with equations or method of determining the slope of the Tafel plots generated. Thank you
You can plot the Linear sweep voltammetry and get the values of Ecorr and Icorr from the graph and calculate the corrosion rate by the standard formula .
Dear Dr. Ilesanmi O. OLOFINTUYI ,
as I wrote in a previous, similar question, I suggest you to have a look at the following, interesting documents:
-Application Note CORR-1 – Basics of Corrosion Measurements by Princeton Applied Research
Available at: https://www.ameteksi.com/library/application-notes/princeton-applied-research
-Application Note - Getting Started with Electrochemical Corrosion Measurement by Gamry Instruments
Available at: https://www.gamry.com/assets/Application-Notes/Getting-Started-with-Electrochemical-Corrosion-Measurement.pdf
-Tafel Plot and Evans Diagram by Palmsens
Available at: https://www.palmsens.com/knowledgebase-article/tafel-plot-and-evans-diagram/
Enjoy reading and my best regards, Pierluigi Traverso.
