To improve surface fatigue strength is very important in machine elements in rolling-sliding contact, such as gears. Although the surface roughness is considered to cause detrimental effects, the directivity of the texture has the effects of promoting an oil film formation and of improving the pitting durability. Also, the directivity of the periodic structures, which were generated on the surface by linear polarized femtosecond laser, influences the lubricating characteristics in sliding contact. In this report, the authors examined the effects of such periodic structures on pitting durability in rolling-sliding contact. As a result, we found a great pit and heavy scar on the follower of ground-ground roller pair, by contrast a few pits of much smaller size were merely found on follower of ground-periodically structured roller pair. The results demonstrate the great effect of such periodic structures on the pitting durability in rolling sliding contact.
