本文利用Nd:YAG固体脉冲激光对GCr15钢样品表面进行了微坑织构化处理,考察了激光表面织构参数对其摩擦性能的影响,同时通过扫描电镜等对磨斑表面进行了分析.结果表明:与光滑面试样相比,经织构化处理的样品表面在干摩擦条件下虽然摩擦系数较高,但表现出了较好的抗磨性能;在贫油润滑条件下,织构面的摩擦系数与磨损均明显小于光滑面;在低载低速下较小孔径织构面摩擦系数较小,随着速度及载荷的增大,较大孔径织构面表现出更好的摩擦学性能.采用Stribeck曲线探讨了织构化表面与光滑面在贫油润滑下的润滑机理,结果表明织构面在试验条件下均保持油膜流体润滑状态. In this paper, we use the Nd: YAG solid pulsed laser to micro-pitted the surface of GCr15 steel samples, and study the influence of the laser surface texture parameters on the friction properties, and analyze the surface of the wear scar by scanning electron microscopy, etc. Results The results show that, compared with the smooth surface sample, the textured surface of the sample has better anti-wear performance under the condition of dry friction. Under the conditions of lean oil lubrication, the textured surface The coefficient of friction and the wear are obviously less than those of the smooth surface. The friction coefficient of the smaller-aperture textured surface is smaller at low load and lower speed, and the larger-aperture textured surface shows better tribological properties with the increase of velocity and load The Stribeck curve was used to investigate the lubrication mechanism of textured surface and smooth surface under lean oil lubrication. The results show that the textured surface maintains the oil film under the experimental conditions.
