Outline of Final Research Achievements

We have studied to sophisticate the technology for thin film fluid lubrication utilizing nanostripe structure. The measurements were made on (1) the friction force distribution by an AFM and the mesoscale friction test apparatus, (2) the friction properties for low sliding speed and for combination of pattern surfaces, (3) the friction force and change in lubricant oil thickness using the rotation friction tester,. For (1), it was found that there is a difference in the friction reduction effect depending on the direction of the groove and that the friction force reduced on the nano grooves. For (2), the friction coefficient could be increased by combining the patterns. For (3), it became clear that the friction efficiently reduced for patterns with the higher ratio of the nano-pattern area. Throughout the research, we were able to obtain new findings on the lubricating properties of the nanoscale patterns.
