title = "Localized coating failure on AA2024-T3 in different electrolyte environments",
abstract = "Epoxy-coated AA2024-T3 samples were exposed to solutions of variable chloride concentration and pH. Underfilm corrosion processes were monitored in-situ with confocal laser scanning microscopy. In near-neutral solutions, both pitting at intermetallic compounds and within the alloy matrix were observed during blister formation and growth. Evidence for anodic undermining / corrosion product wedging was obtained. In addition general corrosion of the matrix led to a strong roughening of the surface. In acidic NaCl solutions, localized corrosion was observed at the original blister site. Thereafter, general attack on the Al-matrix near the original blister was more important than intermetallic particle corrosion. In acidic sulfate solutions, the coating started to fail at many locations on the sample at the same time. This more global failure is in agreement with electrochemical impedance measurements, and the observation of numerous blisters on large-area panels.",
