Abstract—

In recent years, the use of laser nanotechnology has led to numerous breakthrough results in materials science for creating multifunctional coatings. In this work, based on the application of laser methods for processing the surface of an aluminum alloy, multifunctional coatings with hierarchical roughness combining micro- and nanotexture are obtained. It was shown that, after chemisorption of fluorosilanes, the developed coatings possess superhydrophobic properties that persist under various mechanical loads and UV irradiation. It was found that, after long-term structure-damaging effects, coatings are characterized by self-healing. Owing to detailed selection of the modes of interaction of the laser beam with the material, it was possible to increase significantly the rate of coating production without compromising the functional properties.

铝合金的激光处理以制备耐候性超疏水涂层

摘要-

近年来，激光纳米技术的使用已在用于创建多功能涂层的材料科学领域取得了许多突破性成果。在这项工作中，基于激光方法在铝合金表面处理中的应用，获得了具有微米级和纳米级纹理的分级粗糙度的多功能涂层。结果表明，在氟硅烷化学吸附后，已开发的涂料具有超疏水性能，可在各种机械负载和紫外线照射下持续存在。已经发现，在长期的结构破坏作用之后，涂层具有自我修复的特征。由于详细选择了激光束与材料的相互作用方式，因此可以在不损害功能特性的情况下显着提高涂层的生产速度。
