Stainless steel (SS) has long been widely used in the outdoor environment as engineering material due to its excellent corrosion resistance. Recently it is found that super-hydrophobicity on the stainless steel surface also has significant effect on its corrosion resistance. In this work, laser surface texturing (LST) and decoration of hexadecyltrimethoxysilane (HDTMS) duplex treatment were carried out to improve the super-hydrophobicity and corrosion resistance of AISI 304 SS. Comparative appraisals of super-hydrophobicity and corrosion resistance for the related samples were conducted via wetting behavior with distilled water and electrochemical performance with simulated haze solution. The surface morphologies of ground 304 SS (G-304 SS), HDTMS + ground 304 SS (HG-304 SS), surface textured 304 SS (T-304 SS) and HDTMS + surface textured 304 SS (HT-304 SS) before and after electrochemical tests were obtained by scanning electron microscope (SEM). The results showed that micropores with different designed distances have distributed on the surfaces of 304 SS samples after LST treatment. When the micropore distance was 50 μm, this HT-304 SS exhibited a highest contact angle of 158.9°. Electrochemical experiments revealed that the HT-304 SS suggested better corrosion resistance in comparison to the G-304 SS, HG-304, and T-304 SS samples, which was mainly due to its outstanding super-hydrophobicity property.

不锈钢（SS）由于其优异的耐腐蚀性，长期以来一直在室外环境中用作工程材料。最近发现，不锈钢表面上的超疏水性也对其耐腐蚀性具有显着影响。在这项工作中，进行了激光表面纹理化（LST）和十六烷基三甲氧基硅烷（HDTMS）双重处理的装饰，以改善AISI 304 SS的超疏水性和耐腐蚀性。通过蒸馏水的润湿行为和模拟混浊溶液的电化学性能，对相关样品的超疏水性和耐腐蚀性进行了比较评估。地面304 SS（G-304 SS），HDTMS +地面304 SS（HG-304 SS）的表面形态 通过扫描电子显微镜（SEM）获得在电化学测试之前和之后的表面织构化的304 SS（T-304 SS）和HDTMS +表面织构化的304 SS（HT-304 SS）。结果表明，经过LST处理后，304 SS样品表面具有不同设计距离的微孔分布。当微孔距离为50μm时，该HT-304SS表现出158.9°的最高接触角。电化学实验表明，与G-304 SS，HG-304和T-304 SS样品相比，HT-304 SS具有更好的耐腐蚀性，这主要是由于其出色的超疏水性。结果表明，经过LST处理后，304 SS样品表面具有不同设计距离的微孔分布。当微孔距离为50μm时，该HT-304SS表现出158.9°的最高接触角。电化学实验表明，与G-304 SS，HG-304和T-304 SS样品相比，HT-304 SS具有更好的耐腐蚀性，这主要是由于其出色的超疏水性。结果表明，经过LST处理后，304 SS样品表面具有不同设计距离的微孔分布。当微孔距离为50μm时，该HT-304SS表现出158.9°的最高接触角。电化学实验表明，与G-304 SS，HG-304和T-304 SS样品相比，HT-304 SS具有更好的耐腐蚀性，这主要是由于其出色的超疏水性。
