The tribological behavior of femtosecond laser-textured leaded brass samples under five surface roughness and four lubrication conditions were studied. The results have shown that under a variety of lubrication conditions, the coefficient of friction of laser-textured leaded brass exhibited consistent changes. As the roughness increased, the friction coefficient first increased and then decreased. Under a variety of friction conditions, the surface roughness was different when the friction coefficient was the smallest. Under the conditions of dry friction, water lubrication, starved-oil lubrication, and oil lubrication, the maximum reduction ratio of the coefficient of friction was 13.28%, 27.64%, 8.09%, 10.79%. The wear mechanism was mainly adhesive wear and abrasive wear, but there were also differences in specific wear mechanisms. Corrosive wear still existed under the water lubrication. The wear area of the laser-textured surface was larger than that of the unprocessed surface. According to the above sequence, except for water lubrication, the maximum reduction ratio of the wear area was 8.54%, 51.35%, and 88.39%.

研究了飞秒激光纹理化含铅黄铜样品在五种表面粗糙度和四种润滑条件下的摩擦学行为。结果表明，在多种润滑条件下，激光织构含铅黄铜的摩擦系数表现出一致的变化。随着粗糙度的增大，摩擦系数先增大后减小。在各种摩擦条件下，摩擦系数最小时表面粗糙度不同。在干摩擦、水润滑、缺油润滑和油润滑条件下，摩擦系数的最大降低率为13.28%、27.64%、8.09%、10.79%。磨损机制以粘着磨损和磨粒磨损为主，但具体磨损机制也存在差异。水润滑下仍存在腐蚀磨损。激光纹理表面的磨损面积大于未加工表面的磨损面积。按上述顺序，除水润滑外，磨损区的最大减少率为8.54%、51.35%和88.39%。
