To enhance the friction and hydrophobic performances of contact interfaces, the laser-induced periodic surface structures (LIPSS) by picosecond pulses and atomic layer deposition (ALD) MoS₂ nano-coatings are fabricated on the cement carbide surface. The friction and wettability tests are carried out by the unidirectional sliding friction and sessile drop experiments. Results show that the friction and wetting properties can be regulated by the LIPSS and ALD MoS₂ nano-coatings, and the anisotropic friction and hydrophobic properties are observed with respect to the groove orientations. A combination of ALD MoS₂ nano-coatings with LIPSS in parallel orientation (MS-HT) exhibits the best potential for improving the friction and wear performance, and the ALD nano-MoS₂ coated surface combined with LIPSS in perpendicular to the observation direction (MS-VT) is the most effective way for enhancing the hydrophobic property.

为了增强接触界面的摩擦和疏水性能，在硬质合金表面上制作了皮秒脉冲激光诱导的周期性表面结构（LIPSS）和原子层沉积（ALD）MoS ₂纳米涂层。摩擦和润湿性测试是通过单向滑动摩擦和固着试验进行的。结果表明，可以通过LIPSS和ALD MoS ₂纳米涂层调节摩擦和润湿性能，并观察到相对于沟槽取向的各向异性摩擦和疏水性能。ALD MoS _2的组合具有平行取向的LIPSS的纳米涂层（MS-HT）表现出改善摩擦和磨损性能的最佳潜力，与LIPSS垂直于观察方向（MS-VT）结合的ALD纳米MoS ₂涂层表面是最有效的增强疏水性的方法。
