英文摘要This study delves into the corrosion behavior of riveted joints with electrophoretic treatment in a neutral salt spray environment using tensile test and surface analysis. The results showed that the open-circuit potentials of the dual-phase steels (590DP and 780DP) exceeded those of the AlSi10MnMg-T7 and JDA1b die-casting aluminum alloys by 100 mV, and exceeded that of the AA6063-T6 extruded aluminum alloy by 50 mV. AlSi10MnMg-T7 and JDA1b die-casting aluminum alloys were more susceptible to corrosion in contrast to the AA6063-T6 extruded aluminum alloy. The corrosion mechanism of the steel/aluminum riveted joints was not only galvanic corrosion but also oxygen concentration polarization. Over the 720-h corrosion period, the failure loads of the riveted joints were not reduced at all. On the contrary, they increased at least 17% for the two-sheet self-piercing riveting (SPR) joints, 6% for the three-sheet SPR joints, and 4% for the flow drill screw joints. This study delves into the corrosion behavior of riveted joints with electrophoretic treatment in a neutral salt spray environment. After 720 h of corrosion, the failure loads of the riveted joints were not reduced. Furthermore, the failure loads of all riveted joints were increased, with at least 17% for the two-layer sheet self-piercing riveting (SPR) joints, 6% for the three-layer sheet SPR joints, and 4% for the flow drill screw joints.image
