Fluororesin exhibits low friction by making a transfer film, which leads to sliding of the same kind between fluororesins, on the counterpart surface. In this study, in order to improve in both fluororesin transfer ability and retention ability, periodic structures with submicron scale periodical pitch and groove depth were formed on the counterpart surface. The effects of the periodic structures on transfer of fluororesin and friction coefficient were verified. As a result, it was confirmed that the periodic structures oriented along the sliding direction are effective in reducing friction, wear and adhesion because of firm fluororesin transfer film formed on the periodic structures.
