Abstract
The present paper investigates the effect of corrosive environments on the degradation and mechanical properties of Self-Piercing Riveting (SPR) joints between dissimilar metals. The investigations were carried out on a lap-shear joint of 5182 aluminium with pure zinc (GI), and a zinc––aluminium––magnesium (ZM or PosMAC® 1.5) coated 590DP steel. The experimental results show that corrosion significantly influences the lap shear performance and failure mechanism of the joint depends on the type of coating and pre-treatment with and without primed (80% zinc, 10% aluminium). Detailed microstructural analysis of the SPR specimen and coating reveal the actual mechanism for mechanical property degradation. In ZM coated steel the formation of Mg2+ and Al3+ ions delay transformation of basic zinc salts to ZnO, and thereby retard the rate of corrosion. The experimental evidence supports the proposition that ZM coated steels have four-times superior corrosion resistance compared to zinc-coated
steels.
