Smart Corrosion Monitoring in AA2055 Using Hidden Markov Models and Electrochemical Noise Signal Processing by Martínez Ramos, Cynthia, Gaona Tiburcio, Citlalli, Estupiñan López, Francisco Humberto, Cabral Miramontes, José Ángel, Maldonado Bandala, Erick, Almeraya Calderón, Facundo, Nieves Mendoza, Demetrio, Baltazar Zamora, Miguel Ángel, Landa Ruiz, Laura, Galván Martínez, Ricardo, Almeraya Calderón, Facundo

“…This work explores the application of Hidden Markov Models (HMMs) for the classification and reconstruction of corrosion mechanisms in the aerospace-grade aluminum alloy AA2055 from the signals obtained by electrochemical noise (EN) analysis. Using the PELT algorithm to segment the signal based on relevant changepoints, distinct corrosion states within the segments are isolated and identified, including general, localized, and mixed corrosion based on statistical signal features, which are used to create the probabilistic structure of HMMs through the initiation, transition, and emission matrices. …”
