(1) Fabrication of functional coatings by suspension plasma spray and controlling microstructure
(2) Fabrication of functional coatings by cold spray process and clarification of deposition mechanism
Theme1：Fabrication of functional coatings by suspension plasma spray and controlling microstructure
Suspension spray process uses suspension (fine particles and liquid) as the feedstock. This research aims to fabricate functional ceramic coatings and investigate the controlling factor to form dense or columnar structures.
Theme2：Fabrication of functional coatings by cold spray process and clarification of deposition mechanism
Cold spray deposition is a coating fabrication technique that uses the supersonic gas stream to accelerate the feedstock particles. It is purely a solid phase deposition method hence, no melting of feedstock material. For the case of titanium dioxide coating, the high photocatalytic anatase structure can be retained in the coating with cold spraying. However, cold spraying ceramic materials is well known to be difficult. In cold spray, plastic deformation of feedstock particles is required for adhesion to the substrate. However, it is difficult to plastically deform hard and brittle ceramic materials, such as titanium dioxide. This study aims to fabricate ceramic coatings through cold spray process and clarify the deposition mechanism.
Theme3：Fabrication of functional coatings by aerosol deposition process
Aerosol Deposition is a promising process for fabrication of thick and dens ceramic coatings. Therefore, this process has been developed for fabrication of ceramic coatings especially PZT coatings for MEMS devices. However, the deposition mechanism of the sprayed solid ceramic particles has not been clarified yet. The deposition mechanism is essential to improve the process and equipment. This study aims to fabricate functional coatings through aerosol deposition process and clarify the deposition mechanism.
