摘　　要：为了研究微造型表面三维形貌表征参数与表面摩擦特性之间的相关关系,运用激光打标系统分别在4组柱体状金属圆盘圆周表面加工微造型,使用三维形貌参数对微造型表面进行量化表征,并在摩擦试验机上进行线接触滑滚状态下的摩擦试验。结果显示:摩擦系数随载荷的增大而减小,随转速的增大而增大。随着微造型面积占有率的增加,摩擦系数先减小后增大;当微造型面积占有率为18%时,摩擦系数最小,说明此面积占有率的微造型表面具有良好的减摩效果。In order to study the correlation between the three-dimensional profile characterization parameters of the micromodeling surface and the surface friction characteristics,the laser marking system was used to process the micro-modeling on the circumferential surface of the four groups of cylindrical metal discs,the three-dimensional profile parameters were used to process the micro-modeling surface,and the friction test was carried out on the friction tester under the condition of line contact sliding.The results show that the friction coefficient decreases when the load increases,and increases when the speed goes up.As the occupancy rate of the micro-modeling area increases,the friction coefficient first decreases and then increases;when the occupancy rate of the micro-modeling area is 18%,the friction coefficient is the smallest,indicating that the micro-modeling surface with this area occupancy rate has a good anti-friction effect.
