The techniques of Auger electron spectroscopy (AES) and x‐ray photoelectron spectroscopy (XPS) have been used to study the locus of failure of epoxy resin joints. The effects of a long water immersion and the application of a silane‐based primer have also been studied. Results indicated that for dry joints fracture occurred near an epoxy resin/metal interface while with water‐soaked unprimed joints, fracture occurred interfacially between the adhesive and iron oxide. The application of the primer to the metal surface prior to bonding prevented the formation of a water‐formed oxide although fracture was then found to occur through the primer.
