Outline of Final Research Achievements

The solid-phase bonding process, such as cold spraying, is an entirely new material formation process. To make this technology practical, we have to understand the bonding mechanism and to guarantee the strength and reliability of them. Combining a macro-scale evaluation by Laser Shock Adhesion Test and micro-scale evaluation technique enables us to understand solid-state bonding phenomena from a multi-scale perspective.

Academic Significance and Societal Importance of the Research Achievements

コールドスプレー法で粒子が付着するメカニズムを実験的に証明することができた.この知見をもとに今後は固相接合技術で取り扱える材料種の拡大,全く新しいプロセス開発などが期待される.また,この現象を理解するために必要なマルチスケールな材料強度評価技術を確立した.今後は固相接合材料以外の表面改質技術への応用展開,そして材料強度を幅広いスケールで理解できる学術分野構築への貢献が期待される.
