“…Calabrese et al [165] studied the influence of alternate immersion corrosion on the mechanical performance of various AA6082 aluminium alloy stacks joined by steel rivets with a zinc coating. The alternate immersion test was carried out, according to the ASTM G44 standard, using an automated alternate immersion tank.…”

“…The AA6082 had a more negative corrosion potential of Fig. 42 The polarization curves for the rivet and the aluminium alloy sheet in a 3.5% NaCl solution [165] −1500 mV than the rivet (zinc coating) (−1300 mV), but the AA6082 can be passivated to a pitting point of −700 mV. The lap shear strength of the joints after the corrosion showed that the joints degraded due to crevice and pitting corrosion and the joint strength reduced gradually with the increase of corrosion time.…”

Self-piercing riveting (SPR) is a cold mechanical joining process used to join two or more sheets of materials by driving a rivet piercing through the top sheet or the top and middle sheets and subsequently lock into the bottom sheet under the guidance of a suitable die. SPR is currently the main joining method for aluminium and mixed-material lightweight automotive structures. SPR was originated half century ago, but it only had significant progress in the last 25 years due to the requirement of joining lightweight materials, such as aluminium alloy structures, aluminium-steel structures and other mixed-material structures, from the automotive industry. Compared with other conventional joining methods, SPR has many advantages including no pre-drilled holes required, no fume, no spark and low noise, no surface treatment required, ability to join multi-layer materials and mixed materials and ability to produce joints with high static and fatigue strengths. In this paper, research investigations that have been conducted on self-piercing riveting will be extensively reviewed. The current state and development of SPR process is reviewed and the influence of the key process parameters on joint quality is discussed. The mechanical properties of SPR joints, the corrosion behaviour of SPR joints, the distortion of SPR joints and the simulation of SPR process and joint performance are reviewed. Developing reliable simulation methods for SPR process and joint performance to reduce the need of physical testing has been identified as one of the main challenges.

“…The aim of Calabrese et al's work [12,13] is to evaluate durability behavior and performances of symmetrical or unsymmetrical SPR joints of aluminum alloy sheets. Long-term ageing tests were performed to evaluate the durability of the mechanical joint in critical environmental conditions such as in salt spray environment.…”

Self-piercing riveting is a relatively new high-speed mechanical joining technique. The present paper deals with the join-ability of similar and dissimilar titanium sheets by self-piercing riveting and the mechanical properties of the self-piercing riveted joints. Tensile-shear tests were carried out to characterize the mechanical properties of different self-piercing riveted joints made of the similar titanium sheets and the dissimilar metal sheet combinations. The normal hypothesis tests were performed to examine the rationality of the test data. The load-bearing capacity, energy absorption, and failure modes of different titanium sheet self-piercing riveted joints were studied. Results showed that the load-bearing capacity of self-piercing riveted joints with titanium as upper sheets are higher than that of the self-piercing riveted joints with titanium as lower sheets.

“…Accelerated ageing tests (i.e. salt fog test) were carried out to evaluate the durability of the joints in highly aggressive environments (Calabrese et al 2013;LeBozec et al 2012). Although the durability for a long time of the clinched joint in a corrosion environment is a known problem, few works focus the attention on the relationship between durability of joints and electrochemical behaviour of the metal constituents.…”

Background: The clinching is one of the most common metal joining processes in the manufacturing of metal plate based products (similar or dissimilar, pre-coated or galvanized), especially when the assembly without adding major joining elements is required. When the clinched joints work in an aggressive environment, particular attention would be placed on the electrochemical stability and corrosion resistance of the metal constituents (Mizukoshi and Okada 1997). In joining design, an appropriate material selection reduces the electrochemical potential differences and prevents significant galvanic currents (Kruger and Mandel 2011;. The durability of the metal joints could be heavily influenced in a corrosive environment, whereas the less noble material will tend to increase its corrosion rate; instead the more noble one will reduce its electrochemical dissolution (He et al. 2008;Bardal 2004). Accelerated ageing tests (i.e. salt fog test) were carried out to evaluate the durability of the joints in highly aggressive environments (Calabrese et al. 2013;LeBozec et al. 2012). Although the durability for a long time of the clinched joint in a corrosion environment is a known problem, few works focus the attention on the relationship between durability of joints and electrochemical behaviour of the metal constituents. The aim of the present work is to evaluate the durability at long ageing time in salt spray test (according to ASTM B117) of carbon steel/aluminium alloy joints, obtained by clinching. Methods: The investigation has been conducted on one total thickness (2.5 mm) of unsymmetrical joints (i.e. thickness sheets of 1.5 mm and 1 mm) to inquire about the effect of corrosion on the two different unsymmetrical configurations (St1.5/Al1 and St1/Al.5). The joint resistance has been determined, by means of shear tests of single-lap joints in according to ISO/CD 12996. The samples were exposed to critical environmental conditions following the ASTM B 117 standard. To inquire the damage evolution of the samples, 0, 1, 2,3, 5, 7, 10 and 15 weeks of ageing time have been chosen. Seven samples for each combination and for each ageing time were realized. A Design of Experiment has been performed, followed by the ANOVA of the results to analyse the influence of the two factors, thickness combinations and ageing time, on the mechanical properties of the joints. Results: The two sets of joints show a different behaviour at increasing ageing time: the St1.5/Al1 batch shows a constant decay of the load values, instead the St1/Al1.5 set maintains acceptable values of resistance for several weeks of ageing, at tenth week the mechanical stability is strongly impaired. In the latter case the presence of the thin oxide layer at the overlapping interface, which behaves as an adhesive interlayer, and the larger thickness of the aluminium plate improve the resistance of the St1/Al1.5 joints. Statistical analysis confirms that the two thickness combinations and ageing time are the significant factors. At zero weeks, neglecting ...
