Fabrication of biomimetic superhydrophobic metals has attracted considerable interest because their exceptional surface wettability. Conventional methods for achieving this property often rely on additional organic coatings to lower the energy; however, they are very prone chemical decomposition and even flaking during practical usages. Here, we demonstrated that laser-induced phase transition in hierarchical structures metal can act as an effective approach directly produce effect without any decorations. Through gradual increasing numbers femtosecond laser processing, transfer from initial polycrystalline material into super-nanometer-sized dual-phase three-phase consists nano para-crystallinity embedded amorphous substance, both which contribute lowering energy. Meanwhile, geometrical profiles become richer more complicated improving stability air pockets. Remarkably, it is found mechanical durability such surfaces enhanced significantly based material. This study describes great value inherent properties, provides a different route develop high-performance coating-free surfaces.
