| Abstract Scope |
Bronze is commonly used in functional components for the marine industry, such as springs in boat engines. In this study, a current-assisted treatment was applied to cold-rolled Cu-8 wt% Sn alloys for the modifications of the mechanical property and corrosion resistance in accordance with the microstructural evolution. A maximum micro-hardness reduction of 67.5% was observed in the Cu-8Sn alloy after being treated at 5.0 × 10^4 A/cm^2 for 1 h, given the occurrence of electrical annealing, as evidenced by the electron backscatter diffraction (EBSD) analyses. The thermal benchmark experiment further explored the concurrent phenomena of the athermal electron wind force effect and the thermal Joule heating effect during the current-assisted treatment. Moreover, the corrosion behavior of the current-treated Cu-8Sn alloys was investigated using potentiodynamic polarization (PDP) and electrochemical impedance spectroscopy (EIS) analyses in 3.5 wt% NaCl solution, and the corrosion products and mechanism will be reported in this study. |
