Effect of heat treatment on the electrochemical behavior of AA2055 and AA2024 alloys for aeronautical applications por Rivera Cerezo, Heriberto, Gaona Tiburcio, Citlalli, Cabral Miramontes, José Ángel, Bautista Margulis, Raúl German, Nieves Mendoza, Demetrio, Maldonado Bandala, Erick, Estupiñan López, Francisco Humberto, Almeraya Calderón, Facundo

“…The aim of this work was to investigate the influence of different heat treatments on the electrochemical corrosion behavior of the alloys AA2055 and AA2024 in the presence of three different electrolytes at room temperature, using an electrochemical noise (EN) technique in accordance with the ASTM-G199 standard. In the time domain, the polynomial method was employed to obtain the noise resistance (Rn), the localization index (IL), skewness, and kurtosis, and in the frequency domain, employing power spectral density analysis (PSD). …”
