ABOUT THE SEMINAR
In this SEAM Public Seminar Motohiro Yamada will present how cold spray has been developed as a high-quality coating process.
Feedstock particles are accelerated by a supersonic gas stream at a temperature that is lower than the melting point of the material, resulting in a coating formation from particles in a solid state. This process can form metallic coatings without oxidation under an atmospheric ambient. The deposition of solid particle is based on plastic deformation both particle and substrate. It means that the fabrication of ceramic coating through cold spray is considered to be impossible due to the lack of ductility. Motohiro will talk about his study, where it was possible to deposit titanium dioxide (TiO2) and some ceramic coatings. Unique microstructures of feedstock particles enabled to deposit thick ceramic coating. In this presentation, he will introduce what we know and what we don’t know about the ceramic coating deposition by cold spray.
