Abstract
An experimental investigation was performed to study the effect of surface roughness and oxidation on the shear strength of single-lap-joints of AA6061, AA7075 aluminum alloys and an?AISI 1080 steel?alloy bonded with two different epoxy adhesives. An optimum surface roughness that provided the maximum shear strength was obtained for all the alloys at room temperature. The variation of the shear stress due to the different heat treatment temperatures revealed that the oxides developed on the alloy surfaces adversely affected the adhesive shear strength. The bulk concentration of magnesium of the aluminum alloys were also observed to affect the adhesive shear strength of the joints.
期刊介绍：
Applied Adhesion Science focuses on practical applications of adhesives, with special emphasis in fields such as oil industry, aerospace and biomedicine. Topics related to the phenomena of adhesion and the application of adhesive materials are welcome, especially in biomedical areas such as adhesive dentistry. Both theoretical and experimental works are considered for publication. Applied Adhesion Science is a peer-reviewed open access journal published under the SpringerOpen brand. The journal''s open access policy offers a fast publication workflow whilst maintaining rigorous peer review process.
