Abstract
The pitting corrosion tendency of the as-extruded AA6063 alloy was investigated in this study through immersion corrosion and electrochemical corrosion tests at various aging temperatures. The morphologies of the corroded samples were characterized using OM, WLI, SEM, and TEM. The corrosion resistance of as-extruded alloys with various heat treatments was assessed using an electrochemical workstation and SECM. The surface potential at various positions on the alloy surface was measured using KPFM. The results indicate that as the aging temperature increases, the corrosion mode of the alloy shifts primarily from subcritical pitting corrosion to pitting corrosion. This shift eventually leads to the formation of stable pitting corrosion, and the alloy’s pitting corrosion resistance gradually decreases. Surface potentials vary among different types of second-phase particles, with Mg2Si measuring 1.57 V and β-AlFeSi measuring 2.14 V. The existence of a potential difference between the matrix and the second-phase particles leads to the formation of both crystalline and cathodic pits. As the temperature increases, the number of active sites for pitting corrosion also increases. Longitudinal expansion of the pits takes place along densely packed (100) planes, forming a semi-cubic stepped crystal structure. Lateral expansion of pits occurs parallel to the <001>Al direction, demonstrating filamentous corrosion expansion.
