Abstract

The inadequate resistance to corrosion and wear of Al-based alloys is a major hindrance to their extensive use. Plasma electrolytic oxidation (PEO), a common and efficient coating technique, creates an oxide coating similar to ceramic on the surface of Al-based alloys, thereby improving their ability to withstand corrosion and wear. Studies have shown that PEO treatment can significantly enhance the short-term corrosion and wear resistance of Al-based alloys. To improve the long-term corrosion resistance of PEO coatings, researchers are now exploring the combination of laser processes with the PEO process. Laser processing is a simple yet efficient technique known for its flexibility, precision, and control. Various laser procedures are recognized for their ability to improve the resistance to wear and corrosion of PEO coatings applied on Al substrates and their alloys. Laser melting procedures have the capability to standardize and modify the microstructure of aluminum-based alloys. This review focuses on enhancing the anti-corrosion and anti-wear properties of aluminum alloys through the integration of laser surface treatments with PEO technology.

通过在铝基材上进行激光表面处理，探索 PEO 涂层的磨损、腐蚀和微观结构

铝基合金的耐腐蚀性和耐磨损性不足是其广泛应用的主要障碍。等离子电解氧化（PEO）是一种常见而高效的涂层技术，可在铝基合金表面形成类似于陶瓷的氧化物涂层，从而提高铝基合金的抗腐蚀和抗磨损能力。研究表明，PEO 处理可显著提高铝基合金的短期耐腐蚀性和耐磨性。为了提高 PEO 涂层的长期耐腐蚀性，研究人员正在探索将激光工艺与 PEO 工艺相结合。激光加工是一种简单而高效的技术，以其灵活性、精确性和可控性而著称。各种激光工艺都被公认为能够提高涂覆在铝基材及其合金上的 PEO 涂层的耐磨性和耐腐蚀性。激光熔化程序能够规范和改变铝基合金的微观结构。本综述重点介绍通过将激光表面处理与 PEO 技术相结合来提高铝合金的抗腐蚀和抗磨损性能。
