| Outline of Final Research Achievements |
The application of low-temperature bonding in industrial processes has been explored in an effort to miniaturize electronic equipment. However, low-temperature bonding has been difficult to achieve because of the presence of oxide film. Therefore, an economical method to obtain a high-tensile strength joint at a low temperature and load is required. In previous research showed that surface modification with organic acid decreased the bonding temperature and the deformation in the solid-state bonding of Al and Cu. Therefore, in this investigation, we aimed to obtain a deeper understanding of the effect of surface modification on the performance of a solid-state bonded joint of Al alloy/pure Zn and pure Ti/pure Al. When surface modification is applied, it is clarified that a high-tensile strength joint can be obtained at a low temperature because metallic Zn and Al are exposed as a result of the decomposition of metal salt in the bond interface at a low bonding temperature.
