Superhydrophobic coatings are limited by complex preparation processes and poor mechanical durability in practical applications. In this study, a mechanically robust superhydrophobic composite coating was applied to an aluminum surface that underwent processing with a nanosecond laser (referred to as a superhydrophobic aluminum surface). It exhibits a high water contact angle (WCA) of 158.81°, a low sliding angle (SA) of less than 5°, and excellent self-cleaning ability. The wear test shows its durability, and the corrosion test shows its excellent corrosion resistance. This study provides a framework for the preparation of robust superhydrophobic surfaces that may have potential applications in many fields.
超疏水涂层在实际应用中受到复杂制备工艺和较差机械耐久性的限制。在本研究中，一种机械坚固的超疏水复合涂层被应用于经过纳秒激光处理的铝表面（称为超疏水铝表面）。它具有158.81°的高水接触角（WCA）、小于5°的低滑动角（SA）以及优异的自清洁能力。磨损测试表明了其耐久性，腐蚀测试表明了其优异的耐腐蚀性。本研究为制备坚固的超疏水表面提供了一个框架，该表面可能在许多领域具有潜在应用。
