Durable Ag-Fe3O4/Fe superhydrophobic surface (SHS) with dendritic structures on the galvanic sheet was obtained by chemical etching, deposition and following annealing process. The promising SHS showed fine superhydrophobicity having the water contact angle of 165 and dynamic sliding angle of 2 degrees. Experimental results showed that the obtained SHS sample has excellent properties of anti-corrosion, catalysis, anti-icing, rolling-off and self-cleaning. The conditions of etching, chemical immersion, and annealing to obtain SHS were investigated. Chemical stability and durability of SHS were investigated via storage in air for ten months. The SHS as a catalyst showed long-term stability, catalytic activity, and reusability, as compared to the substrate of the un-annealed surface. It is an effortless and cheap method to fabricate SHS on the galvanic sheet for industrial applications. The SHS has a potential utilization in a diverse range of bio-medicines, chemistry, microfluidics fields, and electronics.
