description | In this work, the influence of pulse frequency on the corrosion resistance of Cu–Zn binary alloy has been investigated by using electrochemical workstation, scanning electron microscope and X-ray diffraction. The results have shown that after the electric pulse treatment, the average grain size in the microstructure of high-zinc binary brass decreased and the corrosion resistance increased. The thickness of dezincification layer decreased from 49.8 to 30.8 µm. The diameter of capacitive reactance arc increased from 741.1 to 2898.0 µm. The corrosion potential increased from −0.2719 to −0.2378 V, and the corrosion current density decreased from 6.3147 × 10−6 to 4.6971 × 10−7 A cm−2 by one magnitude order. |
