多孔質Niめっきを用いたAl/Ni多層粉末材料の発熱特性

Recently, more efficient heating technology, such as local heating, low power consumption and low carbon dioxide emissions, is required in the field of electrode bonding and JISSO (electronics packaging). An Al/Ni multilayer material with a self-propagating exothermic reaction has attracted attention because they are environmentally friendly with no outgassing and are suitable for local heating. In this study, exothermic characteristics of Al/Ni multilayer powder materials with self-propagating exothermic reaction fabricated by aluminum foil and porous nickel plating technique were investigated experimentally. The exothermic reaction properties of Al/Ni multilayer powders prepared by laminated roll bonding milling were compared with two different nickel layer fabrication techniques using nickel foil and porous nickel plating. As a result of the maximum temperature and reaction time measurements during exothermic reaction, the porous nickel plating technique with only 20 passes exhibited superior or better characteristics rather than using the nickel foil technique with 40 passes. It is expected to be a novel and efficient heating source.
