“Room Temperature Impact Consolidation Phenomenon for Advanced Ceramic Coating - Aerosol Deposition (AD) Method”
Dr. Jun Akedo
Director, Advanced Coating Technology Research Center
National Institute of Advanced Industrial Science and Technology (AIST)
Coating processes that are thought to utilize purely collision pressure or impact force such as aerosol deposition (AD) method and cold spray (CS) method are attracting attention. These accelerate microparticles and ultrafine particles by carry gas to several hundred m / sec or more, make them into a jet stream and collide with the substrate, realize dense coating with good adhesion just by supplying purely mechanical energy. It is thought that fine particles of metals and ceramics are macroscopically bonded at room temperature while remaining in a nearly solid state. In fact, it has been confirmed that, in the aerosol deposition method, it is possible to form a dense ceramic thin film or a thick film having a microcrystal structure of several tens of nanometers or less at room temperature and to obtain excellent electromechanical properties. Then, in the field of semiconductor manufacturing equipment, it has been commercialized as an important coating process. This is called "Room Temperature Impact Consolidation (RTIC)". When viewed as a powder forming process, this phenomenon is fundamentally different from a thermal spray coating and shock compaction in which raw material particles are brought into a molten or semi-molten state to obtain bonding between primary particles. In this presentation, the deposition mechanism of the AD process with RTIC phenomenon and the importance of this phenomenon for the future coating technology are explained.
14:45 - 15:30
“Innovations in Thermal Spray and the Future of Propulsion Technology”
Dr. Ann Bolcavage
Engineering Associate Fellow – Coating Materials, USA
Continuing innovations in thermal spray are essential to meet current and future demands in gas turbine engine manufacturing for greater capability and capacity. Coupled with this is a concurrent need for greater understanding and control of these key and supporting processes using the emerging and disruptive tools of digital technologies and knowledge management. Combined, these developments can transform the ability of thermal spray to contribute to the delivery of the next generation of propulsion.

About the Panel Session:
This session will jump start ITSC 2019 with a thoughtful and aspiring panel that will:
- Aspires to be "organized ad hoc" and free flowing in nature; with minimal scripting
- Aspires to be lively and interactive, rather than formal speeches
- Attendees are encouraged to bring questions.
