| Abstract Scope |
Additive friction stir deposition (AFSD), a solid-state additive manufacturing technique, offers several advantages over fusion-based methods. While most prior studies on AFSD have mainly focused on the relationship between mechanical properties and microstructure, this study investigates the electrochemical corrosion behavior of an AISI 1018 carbon steel part fabricated by AFSD. Tafel polarization tests revealed that the corrosion current density increased from 5.98× 10-5± 1.75× 10-6 (A/cm2) to 8.70× 10-5± 5.35× 10-6 (A/cm2) after AFSD indicating an enhancement in corrosion kinetics. Additionally, the electrochemical impedance spectroscopy results confirmed the Tafel tests as the capacitive arc radius and the charge transfer resistance from equivalent circuit decreased after the process. The deterioration of corrosion resistance after AFSD was attributed to the changes in microstructure of the material. |
