EN analysis (ENA) allows assessment of the type of corrosion and rapid determination of the corrosion rate. Microsoft Excel®, an inexpensive and readily available software package, is an excellent tool for performing repetitive calculations, with automation that saves time for the users. It is a useful tool for the analysis of EN data using fast Fourier transform (FFT), a process that is often made repeatedly and, if not automated, is quite laborious. This work presents a step-by-step procedure using Excel to perform these calculations, automating the process of obtaining the spectral electrochemical noise resistance, Importar imagen. This routine was used to analyze experimental potential and current noise data recorded for chalcopyrite. The results were comparable to those obtained for the same set of experimental data using Origin® software. 2020 artículo científico 0100-4670 https://www.redalyc.org/articulo.oa?id=42964416005 https://www.redalyc.org/journal/429/42964416005/ https://www.redalyc.org/journal/429/42964416005/html/ https://www.redalyc.org/journal/429/42964416005/42964416005.epub https://www.redalyc.org/journal/429/42964416005/movil https://doi.org/10.26850/1678-4618eqj.v45.4.2020.p57-70 en http://www.redalyc.org/revista.oa?id=429 Eclética Química application/pdf Universidade Estadual Paulista Júlio de Mesquita Filho Eclética Química (Brasil) Num.4 Vol.45 |
