Dry electrochemical polishing of copper alloy in a medium containing ion-exchange resin.

For different voltages, the corrosion current value followed the order of I 2 V < I 1 V < I 1.5 V < I initial , showing the polishing process led to a positive improvement on the corrosion resistance of the material surface, and its improvement range showed a trend of first increasing, then decreasing, and then increasing with the increase in voltage.
