With the continuous development of Chinese industrialization, metal materials have been widely used in various fields of production and life. The preparation of the biomimetic super-hydrophobic metal surface can not only extend the service life of metal materials in various environments, but also give the material surface self-cleaning, drag reduction, oil-water separation and other new properties. At present, researchers have been able to use a variety of processes to prepare super-hydrophobic surfaces on metal substrates, and the preparation of metal-based super-hydrophobic surfaces has become a hot spot in bionics research. This article firstly introduces the development of the wetting theory, leads to various methods of preparing super- hydrophobic metal surfaces, and further summarizes the advantages, characteristics and surface microstructures of laser processing to prepare super-hydrophobic metal surfaces. On this basis, this research focuses on the laser composite processing technology that combines laser processing technology with chemical etching technology, deposition technology, ion implantation technology, coating technology and oxidation technology in recent years, and the use of laser composite processing technology to prepare the structure and characteristics of the super-hydrophobic metal surface. Laser composite processing can not only form a richer micro/nano composite structure on the metal surface, but also make the metal surface obtain super- hydrophobic properties faster, thereby preparing a stable and durable super-hydrophobic metal surface. In addition, composite processing can reduce the dependence on a single preparation process, expand the processing range and reduce the production cost. The preparation of super-hydrophobic metal surfaces by laser composite processing has huge application potential in practice.
