Abstract :
In this study, corrosion behavior of copper that was deformed by Simple Shear Extrusion (SSE) method was investigated in 3%wt NaCl solution. Modified WilliamsonHall method, applied on the Xray diffraction patterns of the sles, showed that increase in the number of SSE passes led to increasing in the dislocation density in the copper sles. Moreover, such deformed sles exhibited fewer corrosion currents, in the potentiodynamic polarization test results, than that of annealed one. In addition, Electrochemical Impedance Spectroscopy (EIS) test was employed to assess the SSEed copper corrosion performance, and the results revealed that the SSE technique has a beneficial effect on the corrosion behavior of copper in 3 wt% NaCl aquatic solution.
