dc.description.abstractThe study involves tribocorrosive investigation of FSW-AA5052 formed at tool-speeds of 800, 1000, and 1200 rpm and welding-speeds of 60, 80, and 100 mm/min, for which Pin-on-disc tests in conjunction with open-circuit-potential and potentiodynamic-polarization techniques were utilised. For microstructures EBSD, Optical images and XRD were taken. Results revealed that cast (?1.212 V; 332.43 ?m/year), 800 rpm (?1.213 V; 433.51 ?m/year) and 1000 rpm (-1.236 V; 227.45?m/year) welded samples showed better performance than all the 1200 rpm welded samples. Frictional characteristics of 800 rpm (CoF-1.28) and 1000 rpm (CoF-1.32) samples were better than other samples due to uniform and stable passivation. Elemental analysis showed Oxides and Chlorides of Al and Mg formed over the worn surfaces. © 2025 Elsevier Ltd
