PIRATOBA MORALES, ULISES; VERA LOPEZ, ENRIQUE  e  ORTIZ OTALORA, CESAR. BASIC ASPECTS IN THE INTERPRETATION OF THE DIAGRAMS OF ELECTOCHEMICAL IMPEDANCE. Dyna rev.fac.nac.minas [online]. 2010, vol.77, n.162, pp.13-19. ISSN 0012-7353.

Electrochemical Impedance EI is used to interpret the behavior of the electrolyte/electrode interface, and generally the data obtained are adjusted to models of equivalent circuits for its interpretation. In this work we reviewed the basic aspects of the representation through the Bode plots of circuits used in EI, the diagram modification by circuit parameters variation is shows and their application to cold rolled steel experimental data is illustrated.

Palavras-chave : EI; Electrochemical Impedance; Interpretation EI; Electrical Circuits EI.
