Abstract

The galvanic corrosion behaviour of an aluminium/CFRP laminate self-piercing rivet joint and an aluminium/steel blind rivet joint was analysed by finite element simulation. The corrosion potentials of the joint components were determined by electrochemical polarisation in a 5. wt.% NaCl solution, and were subsequently used as the boundary conditions in the simulation. For verification, the joints were immersed in a 5. wt.% NaCl solution for 6 weeks. The results of the simulations were fully in agreement with the results determined from the long-term immersion test. The highest corrosion rates were found at the material interface, which correlate to the highest potential gradients in the simulation. For the self-piercing rivet joint, galvanically induced pitting corrosion was found on the aluminium alloy, whereas for the blind rivet joint, no corrosion attack was observed.
