On the basis of a brief introduction to the relevant theories of the superhydrophobic surfaces, this review focuses on the development of key technologies in the fabrication process of metal-based superhydrophobic surfaces, attaching particular importance to the analysis of the current status of different fabrication methods, including the core points of surface preparation process, design and construction of micro-/nano-topography, modification with low-surface-energy materials, improvement of surface property, etc. The application status of metal-based superhydrophobic surfaces in various engineering fields, including self-cleaning, metal anti-corrosion, underwater drag reduction, etc., has been summarized systematically, and the key factors affecting the mechanical stability of superhydrophobic surfaces have been pointed out. Moreover, the challenges and issues need to be faced during the development of fabrication process are also discussed. This work is expected to present reference background for advancing the practically engineering application of large-area metal-based superhydrophobic surfaces.
