“…The ES shows a scalloped surface that is typical of an etched and desmutted Al alloy surface. The PS shows aligned coarse intermetallic particles, and these particles are Cu‐ and Fe‐rich . They are cathodic to the matrix and will cause the formation of trenches and cavities when the alloy is exposed to a corrosive environment …”

“…Despite the lack of research studying the cutting parameter influence on corrosion behavior of machined parts, several studies revealed that low cutting speed and high feed values result in machined parts with lower corrosion resistance [35][36][37]. In addition, the surface microhardness has a close connection with corrosion resistance.…”

“…The development of techniques for in situ characterization of localized electrochemical activities has helped to add more insight into the understanding of SLC initiation and propagation. A few studies have successfully employed techniques such as scanning electrochemical microscopy (SECM) [16], scanning vibrating electrode technique (SVET) [17][18][19] and localized electrochemical impedance spectroscopy (LEIS) [20] to reveal the corrosion modes and the regions that are most susceptible to corrosion in friction stir weldments. Thus, in this work, localized electrochemical techniques including the SVET and LEIS have been employed to reveal the difference between the corrosion behaviour of the advancing and retreating sides of the friction stir weldment of the AA2024-T3 alloy.…”
