In order to improve the corrosion resistance and mechanical properties of 7N01 Al alloy, the microstructure, corrosion resistance and mechanical properties of 7N01 Al alloy in processing stage were studied by the combination of electropulse solution treatment[DK](EPT) and DC two-stage aging treatment. The results indicate that after EPT, the self-corrosion current density of the 7N01 Al alloy sample decreases by 82.4%, thereby enhancing its corrosion resistance, and although the plasticity is favorable, there is a reduction in strength; After subsequent DC, corrosion resistance improves by 69.4% compared to the untreated sample, and while there is a slight grain growth, the strengthening phase is re-precipitated, giving a tensile strength higher than that after EPT alone. The EPT + DC process effectively enhances the microstructure and properties of the 7N01 aluminum alloy, which provides theoretical support and technical reference for the electrical treatment of metallic materials.
