“…Based on the preparation technologies, various methods were applied to fabricate superhydrophobic steel surfaces, such as electrodeposition, Layer by Layer deposition, electro‐less galvanic deposition, nanocasting technique, sol–gel, and chemical etching . Various materials, which act as an anti‐corrosion layer, were coated or deposited on steel surfaces, such as TiO 2 , SiO 2 , CeO 2 , SiC, graphene oxide, (GO) and silanes . However, developing new methods with highly efficient, low‐cost, large‐scale, and easy‐to‐prepare remain difficult.…”
