We developed a nano-patterning method for "nanostripes" that incorporates deposition of a multilayer film on a microscale slope array and mechanical polishing. This method is used to fabricate a nanostripe structure consisting of two kinds of materials to form a stripe array on a silicon substrate. We applied the nanostripes of Au-Fe and Ru-Cu to friction tests to examine the possibility of renewability during the friction. Nano grooves once disappeared by sliding with PAO (poly-a-olefin) but re-emerged during friction with PAO+2%Acid Phosphate Ester.
