Abstract
Continuing efforts have been made towards fretting minimization. Simultaneously, texture studies have also been actively pursued as ways toward solving tribological problems. However, few studies focusing on both fretting and texture have been conducted. Therefore, we conducted fretting tests under lubrication for cross-grooved type textured, dimple textured and mirror-finished surfaces and evaluated their initial running-in periods. Our results showed that cross-grooved type texturing is the most effective for acceleration of the initial running-in period. Furthermore, our numerical analysis of contact pressure on these surfaces showed that the highest local contact pressure occurs when cross-grooved type texturing is used. This indicates that high contact pressure promotes surface plastic deformation that leads to an acceleration of the initial running-in period.
