Abstract: Striated surface textures with different incline angles were manufactured on stainless steel surfaces by electrical machining． The tribological properties of two different texture samples were tested with a tribometer ( UMT-3) ． The friction coefficient of the friction pairs was investigated under dry friction and oil lubrication conditions. The influence of the incline angle of striated surface tex-tures on the friction behavior was analyzed. It is found that the friction coefficient experiences a process of first decrease and then in-crease when the ball sliding on the textured surfaces, that is, the existence of striated surface textures leads to friction coefficient fluctu-ation. Compared with the vertical striated surface texture, the incline striated surface texture results in obvious friction coefficient fluc-tuation, and the fluctuation amplitude relates to the textural incline direction. When the direction of friction is the same as the textural incline direction, the fluctuation amplitude is greater than that in the opposite direction.
