The water adhesion of a superhydrophobic surface depends on its surface microstructure and chemical composition, which in turn affects its tribological properties. In this paper, a simple and environmentally friendly method was employed to fabricate superhydrophobic aluminium surfaces with different water adhesion. The results confirmed that the superhydrophobic aluminium surfaces with different water adhesion had different tribological properties under dry friction and water lubrication conditions. The sticky superhydrophobic sample with high adhesion had better wear resistance and lower friction coefficient than the slippery superhydrophobic one with very low adhesion. In addition, the related tribological properties were analyzed. This study is helpful to understand the tribological properties of superhydrophobic surfaces with different water adhesion more clearly, which is of great significance for their practical application.

具有极高和极低水粘附性的超疏水铝表面的摩擦学特性

超疏水表面的水附着力取决于其表面微观结构和化学成分，这反过来又会影响其摩擦学性能。在本文中，采用一种简单且环保的方法来制造具有不同水附着力的超疏水铝表面。结果证实，具有不同水附着力的超疏水铝表面在干摩擦和水润滑条件下具有不同的摩擦学性能。具有高粘附力的粘性超疏水样品比具有极低粘附力的光滑超疏水样品具有更好的耐磨性和更低的摩擦系数。此外，还分析了相关的摩擦学特性。
