为了改善碳化硅在水中的润滑性能，在碳化硅表面间歇交替形成了对称的双向旋转螺旋周期结构。这些亚微米尺度的周期性结构是在低注量(略高于烧蚀阈值)的线偏振飞秒激光照射的表面上以自组织方式形成的。在盘的滑动面上形成的周期性结构。通过环盘试验考察了周期性结构对摩擦系数的影响。实验表明，双向旋转的对称螺旋周期结构加速了磨合过程，并获得了较低的摩擦系数μ
In order to improve the lubrication properties of silicon carbide (SiC) in water, symmetrically spiral periodic structures for bi-directional rotation were intermittently and alternately produced on the surface. These periodic structures of submicron size develope in a self-organized fashion on a surface illuminated by linearly polarized femtosecond laser pulses with a low fluence (slightly above the ablation threshold). The periodic structures formed on the sliding surface of the disk. Ring-on-disk tests were performed to investigate the influence of the periodic structures on the friction coefficient. The experiment showed that the symmetrically spiral periodic structures for bi-directional rotation accelerated the running-in process and achieved a low friction coefficient, μ
