Localized impedance measurements of AA2024 and AA2024-T3 performed by means of AFM in contact mode

Abstrakt

Purpose: The purpose of this paper is to present the results of an atomic force microscopy (AFM) based approach to local impedance spectroscopy (LIS) measurement performed on AA2024 and AA2024-T3 aluminium alloys. Design/methodology/approach: AFM-LIS measurements were performed ex-situ without the electrolyte environment, so in fact the electrical not electrochemical impedance was obtained. Findings: Relative local impedance values recorded for AA2024 alloy during the researches carried out were maximally approximately three orders of magnitude higher than the ones obtained for age-hardened AA2024-T3 alloy. Moreover, in the case of AA2024-T3 alloy, a region located in the interior of α crystals exhibited localized impedance one order of magnitude higher than that measured at its grain boundary when affected by intergranular corrosion. Originality/value: The paper presents differences in localized impedance between grain and grain boundaries activity.
