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.

氧化和表面粗糙度对单搭接金属试件抗剪强度的影响

通过试验研究了表面粗糙度和氧化对AA6061、AA7075铝合金和铝合金单搭接接头抗剪强度的影响。AISI 1080钢?合金用两种不同的环氧粘合剂粘合。在室温下获得了提供最大抗剪强度的最佳表面粗糙度。不同热处理温度对剪切应力的影响表明，在合金表面形成的氧化物对粘接剪切强度有不利影响。铝合金中镁的体积浓度对接头的粘接抗剪强度也有影响。
