Abstract

In this study, a multi-stage sandblasting and acid-etching processing method is used to prepare a 304 stainless-steel surface with a loose structure that has the composite properties of superhydrophobicity, low adhesion, anti-icing ability, self-cleaning behavior and corrosion resistance. The surface morphology and chemical constituents of this structure are characterized by scanning electron microscopy and X-ray diffraction, respectively. The results show that the micro-scale roughness and different degrees of porosity in this structure play a key role in its superhydrophobicity. The anti-icing properties and corrosion resistance are characterized by contact-angle measurements and electrochemical workstation analyses, respectively. The results show that superhydrophobicity has positive effects on surface self-cleaning, anti-icing properties and corrosion resistance of 304 stainless-steel.

多阶段加工方法对不锈钢表面复合性能的影响

摘要

本研究采用多阶段喷砂和酸蚀处理方法制备具有疏松结构的304不锈钢表面，该表面具有超疏水性，低附着力，抗冰能力，自清洁行为和耐腐蚀性能。该结构的表面形态和化学成分分别通过扫描电子显微镜和X射线衍射表征。结果表明，这种结构的微观粗糙度和不同程度的孔隙度对其超疏水性起关键作用。分别通过接触角测量和电化学工作站分析来表征防冰性能和耐腐蚀性。结果表明，超疏水性对表面自清洁具有积极作用，
