SURFACE PRE-TREATMENT OF ALUMINUM ALLOYS IMPROVING SURFACE ADHESIVE PROPERTIES

Popis výsledku v původním jazyce

Adhesive bonding is a method often used for bonded joints of aluminum alloys preparation. The surface pre-treatment is strongly influencing bonded joints shear strength. The surface of two aluminum alloys (AlMg3, AlMgSi) subjected for bonded joints preparation were surface pre-treated using one commercially used and two laboratory prepared solutions. Scanning electron microscopy including chemical composition analysis and tensile shear test for analysis of the pre-treated aluminum alloys were used. Surface of both the examined alloys after pre-treatment exhibited similar character regardless analyzed material and used pre-treatment solution. Tensile shear test revealed differences between individual solutions used for material surface-pretreatment. AlMgSi alloy reached higher shear strength then the AlMg3 alloy. Exposure of the bonded joints to the climate conditions simulated in a climate chamber revealed and decisive influence of the environment to the adhesive properties of individual materials, however, also differences in the used adhesives were observed and were shown to be more significant than the pre-treatment conditions.
