| Outline of Annual Research Achievements |
Plasma assistance aerosol deposition (PAD) is a coating technology, the process is based on utilization of of plasma assistance for the fine particles under very high speed. However, it is difficult to understand the PAD bonding mechanism during coating formation due to the deposition of huge number of particles on the same time. In this project I investigate the adhesion phenomenon, bonding mechanism of the 1st single particle with the substrate via deposition of only single particle on the substrate by using multi-layer high speed shutter (to avoid the huge number of particles deposition). Followed by quantitative evaluation of the deposited particle Adhesion strength and peeling behavior by using a nano scratch test. Microstructure observation of the cross-section of the deposited single particle.

Current Status of Research Progress
2: Research has progressed on the whole more than it was originally planned.
Reason
The processing is going steady to clarify bonding mechanism of PAD mechanism by investigate the adhesion phenomenon of the 1st single particle with the substrate via deposition of only single particle on the substrate by using multi-layer high speed shutter.
|
| Strategy for Future Research Activity |
Investigating the particle-substrate interface at atomic level to investigate the factors of interfacial bonding of solid ceramic particle. Chemical analysis of substrate surface before and after particle impacting to fully elucidate the adhesion phenomenon and bonding. Elucidating the adhesion phenomenon in the coating via investigate the interfacial bonding between the solid ceramic particles in the coating.

| Causes of Carryover |
Due to COVID related reason and the maker postponed the order to next year.
