Abstract
The paper presents the results of the static strength test on shear adhesion bonded joints made of aluminum alloy 7075. The tests were of a comparative nature and examined the effect of surface activation using low temperature plasma with non-activated samples. Three types of adhesives were used. Based on the studies, the increase of free sur- face energy for low temperature plasma samples and for 2 of the 3 tested adhesives increased the strength of the joint were observed.
