Data from manuscript: Assessment of the 7075-T6-aluminum-alloy/microalloyed-dual-phase-steel joint for automotive chassis

The corrosion behavior of a 7075-T6 Aluminum Alloy sample (AA7075-T6) and a low-Carbon low-Manganese microalloyed dual-phase steel sample (MADPS) were studied by electrochemical impedance spectroscopy (EIS) and potentiodynamic polarization (PP). The galvanic corrosion resulting from their assembly within a dissimilar joint, was studied by the zero-resistance ammeter technique (ZRA). The tests were conducted at room temperature and pressure (Mexico City) using an aqueous solution of 3% NaCl as electrolyte (pH 5.3) and without deaereating the solution. All tests were repeated more than twice to check the reproducibility. Electrochemical impedance spectroscopy (EIS) and potentiodynamic polarization were conducted using a BioLogic VMP3 potentiostat with EC-Lab software. The samples were pasted to the side of an acrylic cell. Circular sections of 1 cm2 on top of the samples were cut off from the cell to allow electrolyte contact. A typical three-electrode cell arrangement was used, with the ...
