A local electrochemical impedance study of the self-healing properties of waterborne coatings on 2024 aluminium alloy

•Corrosion protection in scratched coatings was investigated by local impedance.•Local diagrams and mappings confirmed the significant inhibition by the chromates.•Mappings at 1kHz indicated good adherence of the coatings on the AA2024 substrate.•Local impedance gave fast response on the efficacy of...
