The invention provides a fairing with a hydrophobic structure, an anti-icing corrosion-resistant coating on the surface of the fairing and a preparation method and application of the fairing. The fairing is of a conical structure, the side conical face of the fairing extends downwards from a conical tip to form multiple layers of umbrella-shaped faces, and texture morphology and/or an anti-icing corrosion-resistant coating are evenly distributed on the outer surface of each layer of umbrella-shaped face. Wherein the anti-icing corrosion-resistant coating sequentially comprises a PTFE (polytetrafluoroethylene) coating chemically modified by a sodium naphthalene treatment liquid and a GO/PPS (graphene oxide/polyphenylene sulfide) composite coating chemically modified by a fluorosilane treatment liquid from inside to outside along the attachment surface. By designing the multiple layers of umbrella-shaped surfaces, the rolling distance of liquid drops on the surface can be shortened, and the liquid drops can be separated from a base body easily. By designing the laser texture on the surface of the substrate, the roughness can be increased, and flow can be guided to be easy to tumble. By designing a multi-layer coating and a surface chemical modification treatment method, the adhesive force of the coating can be improved, a surface micro-nano secondary structure is constructed, and the surface energy is reduced, so that the coating has excellent anti-icing property and corrosion resistance.

    本发明提供了一种具有疏水结构的整流罩、整流罩表面的防结冰耐腐蚀涂层及其制备方法和应用。所述整流罩呈锥形结构,其侧锥面由锥尖向下延伸出多层伞状面,每层伞状面的外表面均分布有织构形貌和/或防结冰耐腐蚀涂层。其中,所述防结冰耐腐蚀涂层沿附着面由内向外依次包括:以钠萘处理液化学修饰的PTFE涂层和以氟硅烷处理液化学修饰的GO/PPS复合涂层。本发明通过设计多层伞状面,可以缩短液滴在表面的滚动距离,利于液滴脱离基体。通过在基体表面设计激光织构,既可以增加粗糙度,又可以导流易于滚落。通过设计多层涂层以及表面化学修饰的处理方法,可以提升涂层的黏附力、构造出表面微纳二级结构和降低表面能,使得该涂层兼具优异的防冰性和耐腐性。
