Abstract
Sn coatings were electrodeposited over mild steel at different current densities (5 mA cmâ��2, 20 mA cmâ��2, 40 mA cmâ��2, 60 mA cmâ��2, and 80 mA cmâ��2). Corrosion resistance was highest for the Sn coating fabricated at 20 mA cmâ��2, and that it decreased as the current density for electrodeposition increased. Electron backscatter diffraction (EBSD) results revealed that a high fraction of low angle grain boundaries (LAGBs), a high fraction of (031)01Ì 3 twin boundaries, a preferred (100) texture, and uniform stress distribution enhanced the corrosion resistance of the 20 mA cmâ��2 coating while the (110) growth texture deteriorated the corrosion resistance of 80 mA cmâ��2 coating. © 2021 Elsevier Ltd
