Durability of orbital riveted steel/aluminium joints in salt spray environment

In this work, aluminium alloy/steel joints were realised with an orbital riveting process. Two series of joints were made; i.e. in the first, the head of rivet touches with the aluminium sheet; in the second, it touches with the steel one. After their manufacturing, during tests were carried out by exposing the joints to a salt spray fog up to 10 weeks into a climatic chamber. Finally, mechanical tests were performed with the aim to know the effect of corrosion on performance and failure.
