Abstract: Metal/polymer joints as well as metal/metal joints bonded by epoxy adhesive have been widely used for automotive, electrical device and others. In the present study, the adhesion strength of a stainless-steel/epoxy joint was evaluated by using of the shear test and the 4-point bending test. Three kind of the surface finishing condition of the stainless steel were selected, and the effect of the surface morphologies of the interface on the adhesion strength in the metal/epoxy joint was investigated. The relationship between the interface morphology and the loading mode in the metal/epoxy joint was discussed.

Abstract: First-principles calculations based on density-functional theory are powerful tools to investigate the structure and properties of ceramic interfaces. The Schottky-barrier heights of SiC/metal and Al2O3/metal interfaces have been examined, and significant effects of the interface stoichiometry (termination species) and metallic species have been found. Ab initio tensile tests have been applied to Al2O3/Cu and Al2O3/Ni interfaces, where the strength and features of failure also greatly depend on the interface stoichiometry and metallic species.
