The anti-icing and drag-reduction properties of diverse microstructured surfaces have undergone extensive study over the past decade. Nonetheless, tough environments enforce stringent demands on composite characteristics superhydrophobic (SHS). In this study, fresh structures were fabricated a metal substrate by nanosecond laser machining technology, drawing inspiration from hardy plant Iridaceae. prepared sample surface mainly consists periodic microrhombus array irregular nanosheets. To comprehensively investigate effect its special structure properties, three with different sizes rhombic used for comparative analysis, results show that SH-S2 is optimal. This can significantly delay freezing time an impressive 1404 s at -10 °C while revealing strategy. addition, rheological experiments determined 300 μm slip length sample, drag reduction rate reaches nearly 40%, which well aligned delayed icing experiments. Finally, mechanical durability was investigated through scratch damage, sandpaper abrasion, reparability trials, melting cycle tests. research presents new approach methodology application SHS polar ship surfaces.
