Influences of previous electrochemical corrosion and chemical corrosion in H2SO4aqueous solution on surface layer softeningduring electrochemical cold drawing (ECD) of Q235 steel bar were investigated. Results indicate that these two corrosionsall further soften the steel during the subsequent ECD and make the ECD to easier conduct, and the effect from the formercorrosion is larger than that from the latter one. Two modes of corrosion can slightly soften or plasticize the bar surfacelayer due to the increased vacancy clusters, but the contribution of this softening or plasticizing itself to the further softeningduring ECD is very limited, and the further softening should be mainly attributed to the relaxation of dislocations throughabsorbing the vacancy clusters and the resulted weakening of work hardening. The current applied during the electrochemicalcorrosion can promote more vacancy clusters to form in a deeper region beneath the bar surface, and thus the relaxingdegree for the dislocations and the influence region are larger than those from the chemical corrosion respectively, resultingin the greater softening.
