Classification of pitting corrosion damage in process facilities using supervised machine learning
The Canadian Journal of Chemical Engineering, Volume 103, Issue 1, Page 153-169, January 2025.Abstract Corrosion is widely known to be a major cause of the failures in process facilities. Prediction of corrosion damage is therefore essential for industries to manage the availability of their assets. This research aims to investigate the application of supervised machine learning methods for the classification of pitting corrosion damage ...
