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.

提出了泡沫键合成铝泡沫的粘结方法。铝泡沫可以粘合而不会崩溃，密度增加。在这项研究中，通过实验研究了泡沫键合的有效性。铜管前体是由铜合金制造的。由于泡沫剂颗粒分散在前体中，因此通过加热来加热前体泡沫。将前体放入两个凹槽的纯铝泡沫中，并在前体的熔点上加热。可以通过泡沫键合粘合两个凹槽的纯铝泡沫。然而，泡沫键合的粘结强度低于粘合剂。悬挂铝和纯铝泡沫之间的粘结区域的显微镜检查。清楚地观察到粘结边界。应考虑表面处理，以便通过泡沫键合获得高粘结强度。
