In this study, I have investigated the dry friction properties of nanostripe structure under a high vacuum condition, (less than 2.0×10-4 Pa) Nanostripe structure has a multilayer consisting of soft metal of Ag and hard metal of Cr. Unpolished and polished nanostripe structures of Ag and Cr were rubbed with SUJ2 ball. Moreover, unpolished nanostripe structure was rubbed with Al2O3 ball under loads of 0.5 N, 3 N, and 6 N. The result showed that friction coefficient for polished nanostripe structures were higher than that of the unpolished one throughout for the friction test. Friction coefficient for unpolished nanostripe structure decreased to 0.15-0.2 after about 3000 oscillations under a load of 6 N. Si plate was rubbed Al2O3 ball with transfer particle under a load of 1 N. Friction coefficient of Si plate by transferred Al2O3 ball was higher than that of one by new Al2O3 ball.
