| Research Abstract |
The foaming bonding was proposed as a bonding method for aluminum foams. The aluminum foams can be bonded without collapse of the cell wall and density increase. In this study, the effectiveness of the foaming bonding was investigated experimentally. The brazing precursor was manufactured from brazing aluminum alloy. The precursor foams by heating because the foaming agent particles were dispersed in the precursor. The precursor was put into two grooved pure aluminum foams and heated over the melting point of the precursor. Two grooved pure aluminum foams can be bonded by foaming bonding. However, the bonding strength with foaming bonding was lower than that of the adhesive. Microscopy of the bonded area between brazing aluminum and pure aluminum foams was carried out. The bonding boundary was clearly observed. The surface treatment should be considered in order to obtain the high bonding strength with foaming bonding.
