📢 𝗡𝗲𝘄 𝗽𝗮𝗽𝗲𝗿 𝗽𝘂𝗯𝗹𝗶𝘀𝗵𝗲𝗱!

ISISE researchers 𝗔𝗹𝗲𝘅𝗮𝗻𝗱𝗿𝗲 𝗥𝗼𝗰𝗵𝗮 and Isabel B. Valente, together with José B. Aguiar (CTAC), have published a new open-access article in Surfaces and Interfaces (Elsevier):

🔬"𝗜𝗻𝗳𝗹𝘂𝗲𝗻𝗰𝗲 𝗼𝗳 𝘇𝗶𝗻𝗰 𝗰𝗼𝗮𝘁𝗶𝗻𝗴 𝗽𝗿𝗼𝗽𝗲𝗿𝘁𝗶𝗲𝘀 𝗼𝗻 𝘁𝗵𝗲 𝗽𝗲𝗿𝗳𝗼𝗿𝗺𝗮𝗻𝗰𝗲 𝗼𝗳 𝗮𝗱𝗵𝗲𝘀𝗶𝘃𝗲𝗹𝘆 𝗯𝗼𝗻𝗱𝗲𝗱 𝗴𝗮𝗹𝘃𝗮𝗻𝗶𝘀𝗲𝗱 𝗖𝗙𝗦 𝗷𝗼𝗶𝗻𝘁𝘀"

Galvanised cold-formed steel (CFS) shows great potential for adhesively bonded structural joints, but how does the zinc coating itself affect bond performance? The study compared continuously and batch hot-dip galvanised substrates under three surface conditions and two structural epoxy adhesives, combining surface characterisation (coating thickness, roughness and surface free energy) with single-lap shear testing.

🔍 𝗞𝗲𝘆 𝗳𝗶𝗻𝗱𝗶𝗻𝗴𝘀:
• Mechanical abrasion was the dominant factor, raising peak shear strength by 25 to 114% and reducing scatter.
• A roughly fourfold thicker zinc coating did not, on its own, change joint strength. Under abrasion, however, the batch galvanised coating was more prone to detachment, shifting failure into the zinc layer.
• Primed joints failed prematurely at the steel–primer interlayer, with up to 60% lower strength.

💡 Takeaway: surface quality control for bonded galvanised steel should go beyond roughness and wettability, and also consider the mechanical integrity of the zinc layer.
