Abstract

<jats:title>Abstract</jats:title> In the present work the electrochemical resistance spectroscopy behavior of aluminum alloy 2024 and 6061 in rainwater, was studied before and after solution heat treatment at room temperature (25 ° C). If the resistance decreases, the corrosion becomes faster, and vice versa. The equivalent circuits was of type Constant Phase Element (CPE) and the highest resistance value gets for alloy 2024 aged at 250 ° C for 2 hours, and the highest resistance value was for alloy 6061 aged at 250 ° C for 1 hour. As for the values ​​of capacitance, the highest amplitude value was for alloy 2024 aged at 300 ° C for two hours, and the highest value gets for capacity for alloy 6061 aged at 150 ° C for two hours.
