Adhesive bonding of hot‐dipped galvanized steel: use of ToF‐SIMS for forensic analysis of failed joints

Abstract: The interfacial chemistry of environmental failure of adhesively bonded hot-dipped galvanized steel joints, fabricated using a structural epoxy in a lap configuration, has been investigated by time-of-flight (ToF) SIMS. The failed lap shear joints show areas of apparent interfacial failure but these regions are limited to thin strips at the ends of the overlap, termed initiation zones. An initial study highlighted the importance of small area surface analysis, using XPS, to demonstrate that electrochemical act… Show more

“…PDMS is a highly surface active lubricant that can cause adhesion failures between layers of a coating. SSIMS has characterized PDMS contamination in many different applications, including atomic force microscopy (AFM) cantilevers, pharmaceutical injection vials, poly(vinyl chloride) (PVC) ion-selective electrode membranes, styrene-butadiene rubber, automotive clearcoats, epoxy adhesives, and poly(vinyl acetate−ethylene) coating on PVC . An example of a SSIMS spectrum showing siloxane surfactant contamination is shown in Figure from Lo and co-workers on an AFM tip .…”
