Corrosion Resistance of Ultrafine-Grained Pure Cu

Article Preview

Abstract:

Pure Cu samples were subjected to equal channel angular pressing (ECAP), and the corrosion resistance of the samples was investigated by potentiodynamic polarization measurements and electrochemical impedance spectroscopy measurements in 3.5% NaCl solution. The results show that the corrosion rate of the ultrafine-grained Cu decreases, in comparison with the coarse-grained Cu.
