研究了飞秒激光烧蚀纳米结构类金刚石薄膜的摩擦学性能。使用为飞秒激光加工开发的精确目标扫描系统，在DLC表面上形成了大于15mm×15mm的纳米结构。通过在纳米结构表面涂覆MoS2层，DLC膜的摩擦性能得到显著改善，而通过在纳米结构区域进行网状图案化的表面织构化，DLC膜的摩擦系数得到提高。结果表明，DLC表面的摩擦学性能可以控制使用飞秒激光诱导纳米结构化。
This paper reports tribological properties of diamond-like carbon (DLC) films nanostructured by femtosecond (fs) laser ablation. The nanostructure was formed in an area of more than 15mm×15mm on the DLC surface, using a precise target-scan system developed for the fs-laser processing. The frictional properties of the DLC film are greatly improved by coating a MoS2layer on the nanostructured surface, while the friction coefficient can be increased by surface texturing of the nanostructured zone in a net-like patterning. The results demonstrate that the tribological properties of a DLC surface can be controlled using fs-laser-induced nanostructuring.
