Frequency–Time Domain Analysis Based on Electrochemical Noise of Dual-Phase (DP) and Ferrite–Bainite (FB) Steels in Chloride Solutions for Automotive Applications by Almeraya Calderón, Facundo, Montoya Rangel, Marvin, Nieves Mendoza, Demetrio, Jáquez Muñoz, Jesús Manuel, Baltazar Zamora, Miguel Ángel, Landa Ruiz, Laura, Lara Banda, María del Refugio, Maldonado Bandala, Erick, Estupiñan López, Francisco Humberto, Gaona Tiburcio, Citlalli

“…At room temperature, the steels were immersed in NaCl, CaCl2, and MgCl2 solutions and were studied by frequency–time domain analysis using wavelet decomposition, Hilbert–Huang analysis, and recurrence plots (RPs) related to the corrosion process and noise impedance (Zn). …”
