| Outline of Final Research Achievements |
In the aerosol deposition (AD) method, which is a technique for producing a coating by colliding particles with a substrate at room temperature, it was tried to produce highly oriented ceramics coatings by the plastic deformation of the particles at collision. Although it depends on the type of powder, it was found that a highly oriented coating was formed by increasing the gas flow rate during coating formation and heat treatment after coating deposition. It was also clarified that a TiN coating produced by AD method shows similar mechanical characteristics than that of the TiN coating produced by the AIP method.

| Academic Significance and Societal Importance of the Research Achievements |
本研究は、高速変形での集合組織形成を理解し、金属での常温・高温での変形に伴う集合組織形成および熱処理による再結晶集合組織の形成の理解をセラミックスにまで拡張するものである。それゆえ、結晶配向に基づいたAD法の成膜原理の理解に繋がると考える。この配向制御法は低温成膜法の一つであるAD法に新たな用途展開の可能性を開くものであり、異方性を積極的に利用したい圧電素子や熱電変換素子など、様々な分野への応用が期待できる。
