Abstract

The effects of the electric pulse treatment on the corrosion resistance of silicon brass are investigated by using an electrochemical workstation and a SEM. The results show that, after the electric pulse treatment, the corrosion potential of silicon brass increases while the corrosion current density decreases by about one order of magnitude, and that the electric field treatment increases the capacitive reactance diameter of silicon brass by 5~6 times and decreases the thickness of dezincification layer from 80~90 μm to 15~20 μm. It is thus concluded that the corrosion resistance of silicon brass alloy is improved after the electric field treatment.

Key words： electric pulse treatment; silicon brass; corrosion resistance; corrosion potential; corrosion current density
