利用电加工的方法在不锈钢表面分别制备了垂直织构和倾斜织构两种条纹织构试样，利用UMT-3摩擦磨损仪研究了具有不同倾斜角表面织构试样的摩擦性能，考察了在干摩擦和油润滑条件下摩擦接触副在织构区摩擦系数的变化情况，分析了条纹织构倾斜角对摩擦性能的影响。结果表明，钢球在织构表面区域滑动过程中，摩擦系数经历了一个先降低后增高的过程，即织构的存在导致了摩擦系数的波动。与垂直织构相比，倾斜织构会导致更明显的摩擦系数波动，且波动幅度与织构倾斜方向有关。当摩擦方向与织构倾斜方向相同时，摩擦系数的变化幅度较反方向更大。

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.
