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°. 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.

耐用的Ag-Fe ₃ O ₄通过化学刻蚀，沉积和随后的退火工艺获得在电板上的具有树枝状结构的/ Fe超疏水表面（SHS）。有希望的SHS显示出优良的超疏水性，其水接触角为165°，动态滑动角为2°。实验结果表明，所获得的SHS样品具有优异的防腐，催化，防冰，降落和自洁性能。研究了蚀刻，化学浸没和退火以获得SHS的条件。通过在空气中储存十个月来研究SHS的化学稳定性和耐用性。与未退火表面的基材相比，作为催化剂的SHS显示出长期稳定性，催化活性和可重复使用性。这是一种在工业用电板上制造SHS的简便而廉价的方法。SHS在生物医学，化学，微流体领域和电子领域的广泛应用中具有潜在的用途。
