This paper describes the concept of fabricating nano-patterned surface on irregular structure. Many researches on friction reduction using micro textured surface has been reported. Almost of them made patterned texture using laser beam machining or etching etc, and clarified that the dimple or groove patterned surface affect on friction reduction. On the other hand, our group is developing the nano scale patterning composed of two kinds of materials on micro patterned surface. This paper proposes to fabricate random texture without micro patterning. The combinations of Fe-Au were deposited on shot blasted surface by physical vapor deposition (PVD). The friction tests were carried out using ball-on-block type machine, and difference of the friction coefficient by the existence of the abrasion was confirmed.
