“…For automotive parts, cathodic epoxy is the most common application. Another means of corrosion protection for steel parts is by zinc plating (Zn-plate) [7] where a zinc-tin alloy is commonly used. This is applied to the steel surface by means of electroplating and protects the steel by acting as a barrier to water/moisture and oxygen.…”

“…In particular, the defect-free PI coating showed a higher and longer protection to corrosion phenomena. Another way to enhance the corrosion resistance is to protect the steel rivet by a zinc coating (Azzerri et al 1982). Krüger and Mandel (2011) have investigated the galvanic corrosion behaviour of two sheets of the aluminium alloys joined by an electrogalvanized zinc blind rivet made of mild steel in a 5 wt.% NaCl solution.…”

Background: Self-piercing riveting (SPR) is a new performing technology able to joint several kinds of metal and non-metal supports together. The combined effect of joint configuration and environmental conditions could have detrimental effect on the ageing effect on mechanical behaviour of dissimilar metal SPR joints. Methods: The joining of dissimilar materials, such as steel and aluminium, realized by self-piercing riveting (SPR) technique was studied to evaluate the ageing effects on its mechanical behaviour in critical environmental conditions. The investigation was carried out on symmetrical or unsymmetrical joints at varying total thicknesses (i.e. 2.0, 2.5 and 3.0 mm). The joint resistance was determined by single-lap shear tests. A design of experiment (DoE) has been performed by using Minitab® followed by the statistical analysis (ANOVA) of the experimental data. Long-term ageing tests in salt spray environment were performed to evaluate the durability of the mechanical joint. Results: The experimental results evidenced that the corrosion degradation phenomena influenced significantly both the performance and failure mechanisms of the joints; also, the joint configuration is a significant factor for the corrosion effect. In the salt spray, the aluminium sheet undergoes a noticeable degradation due to galvanic Al/Fe corrosion. The set characterized by thinner aluminium sheet evidenced a gradual reduction of the mechanical strength with increasing ageing time due to the prevalence of thinning induced by aluminium corrosion. Instead, for S10-A15 samples (characterized by a thicker thickness of aluminium sheet) during the first 7 weeks, stable mechanical performances were observed. Conclusions: The experimental results evidenced that the corrosion degradation phenomena influence significantly both performances and failure mechanisms of SPR joints. Furthermore, the durability of the SPR joint is strongly affected by the joint configuration, and the best results were observed in the unsymmetrical joint with thicker aluminium sheet.

A study examining the effect of coatings on the quality and behaviour of self-piercing riveted joints joining aluminium NG5754 to HSLA350 sheets was conducted. Two types of coatings: E-coated and Zinc plated were applied to the HSLA350 sheet for this study. The results showed that coating affected the joint quality in terms of head height, interlock and remaining material thickness. Examination of joint sections indicated that the self-piercing riveting process needed different setting parameters for coated and uncoated sheets in order to achieve optimum setting conditions. The joint strength was also affected by sheet coatings. However, whether the joints with coated sheet had higher strength was dependent on joint setting conditions. Different coatings had different effects on joint quality and behaviour and different setting conditions led to different behaviour of the joints with or without coatings.
