Superhydrophobic surfaces have been demonstrated to exhibit excellent anti-icing effects, but they are susceptible to the loss of ice repellency as a result of external impacts. This paper proposes a novel bionic armour structure that combines an armour structure with an arrowroot bionic structure. A composite method combining laser etching and chemical modification was employed to achieve superhydrophobicity on the surface of the aluminium alloy. Furthermore, superhydrophobic surfaces with distinctive microstructures were investigated. The findings demonstrated that the contact angles and rolling angles of the second-order armour structure following low surface energy modification reached 158.5° and 3.5°, respectively. Furthermore, the mechanical stability of the surface of the armour step structure was investigated through a sandpaper cyclic wear test. It was observed that conventional micro-cone arrays lost their superhydrophobicity after a single abrasion test, whereas structured superhydrophobic surfaces exhibited a loss of superhydrophobicity after eight abrasion cycle tests. Furthermore, the prepared surface was demonstrated to exhibit excellent anti-icing properties through the simulation and subsequent testing of the delayed icing time of liquid droplets on different surfaces. The icing time of the second-order armoured superhydrophobic surface was found to be 12 times longer than that of the polished aluminium alloy surface. The research presented in this thesis provides new insights into the fabrication of biomimetic superhydrophobic metal surfaces with both good mechanical stability and icing resistance.
