Outline of Final Research Achievements

For friction　reduction and precise positioning, functional friction materials have attracted many interests. (Especially, currently-used DLC coatings and carbon nanotube forests.) In this research, we developed in-situ observational technology for the purpose of understanding the detailed-frictional mechanism of those materials. We clarified that our device is able to observe nano-scale topographical change in frictional interface.
