Outline of Final Research Achievements

It is expected to realize an entirely new solid-phase bonding process, which able to form high-performance materials with lower energy. However, the current technology does not thoroughly understand the nature of bonding, in particular, the ideal bonding energy. Therefore, we developed a micro-strength evaluation technique to establish the micro-scale material strength analysis necessary for correctly understanding the structure, structure, and strength at the bonding interface, and examined the bonding mechanism of the cold spray material. We discovered that the key to developing a new solid-phase bonding process is to generate new surface using small energy and bring the materials into contact with each other.
