摘要：

Surface contamination of an adherend has an influence on its adhesive bonding properties. To investigate this phenomenon, various contaminants, including silicone oil, mineral oil, a fluorine release agent, and surfactants, were quantitatively applied to an aluminium plate (6061) using a spray apparatus. The contaminated adherends were bonded with acrylic and epoxy adhesives, and their adhesion strengths were examined using single lap-shear tests. Mineral oil did not affect the adhesion strength, but silicone oil and surfactant agents were found to significantly affect the adhesion strength. Atomic force microscopy observations and Fourier transform infrared spectroscopy of these surfaces revealed a specific interaction between silicone oil and aluminium.
