Quantitative Corrosion Evaluation and Damage Modeling in Ferrous MaterialsPublic

Quantitatively measuring corrosion effects and understanding the mechanisms are crucial to modeling this phenomenon and preventing it. The goal of this study is to develop a reliable testing and analysis method for quantitative evaluation and prediction of corrosion damage in ferrous materials. A testing apparatus was built in order to study stainless steel samples under various conditions. An original optical methodology for both surface and cross-section damage evaluation was established, along with standard mass measurements. The change in mass showed an asymptotic decrease, whereas surface area damage increased asymptotically. An analytical relationship between corrosion rate and various controlling parameters was ultimately developed for damage prediction in corroded materials.
