The hierarchical structure represents a significant approach to enhance the Cassie stability on superhydrophobic hydrostatic bearing surfaces. However, the preparation of a robust hierarchical structure on tin bronze alloy remains unknown. In the present study, a hierarchical structure comprising micro-bulges and nanowires was fabricated on a tin bronze surface, exhibiting excellent superhydrophobicity (water contact angle, WCA = 163°). In contrast to the micro-bulge structure, the hierarchical structure surface exhibited a quasi-reversible trajectory after pressure, with the WCA recovered to 161°. For the same triple-phase contact line (TPCL), a higher Laplace pressure (3640 Pa) is required to destroy the Cassie state of the hierarchical structure. Droplets on the hierarchical structure can rapidly recover to a stable Cassie state after impact. It can be verified the hierarchical structure has higher Cassie stability to resist pressure, thermal exposure, and impact. The slip lengths of the hierarchical structure in water and VG5 lubricant are 18 μm and 27 μm, respectively. The hierarchical structure preparation is straightforward, and its application to hydrostatic bearings can enhance stability.
