Abstract: The effects of electromagnetic shock on the stress corrosion resistance of 7075 aluminum alloy were studied through conductivity test, residual stress test and electrochemical corrosion experiment. The influence of effective processing time of the pulsed magnetic fields and electropulsing during electromagnetic shock process on the residual stress and stress corrosion resistance of 7075 aluminum alloy were analyzed and discussed. The results show that, compared with untreated samples, when the effective processing time of the pulsed magnetic fields is 60 s and that of electropulsing is 1.0 s, the conductivity of the samples increases from 37.82%IACS to 40.46%IACS, the residual stress decreases from 31.9 MPa to 20.7 MPa, the self-corrosion potential increases from -1.17516 V to -0.96270 V, and the self-corrosion current density decreases from 0.00897 A/cm² to 0.00399 A/cm². The corrosion resistance of the samples and the effect of electromagnetic shock treatment are best. Electromagnetic shock treatment can reduce microcracks, dislocations and other defects in the material, reduce the degree of lattice distortion and residual stress, inhibit the initiation and propagation of stress corrosion cracks and improve the stress corrosion resistance of 7075 aluminum alloy.
