Surface treatments have been widely applied to a variety of metallic materials in order to modify their physicochemical properties and to improve both strength and durability of adhesive-bonded joints. Among available surface treatment methods, laser ablation has the advantages of efficiency, environmental friendliness and easy industrialization. In this work, the principle of laser ablation and its effect on the physicochemical properties of metallic materials are reviewed. The mechanisms accounting for the improved bonding strength and corrosion resistance of the adhesive-bonded joints fabricated from laser-ablated metallic materials are reviewed and discussed. Bonding strength of laser-ablated adhesively bonded joints increases with the increase of roughness and wettability of the metallic adherend surface, and the surface roughness contributes to the improved joint strength only when the adhesive is capable to sufficiently wet the laser-ablated surface to form mechanical interlocking at the bonding interfaces. Although the laser-ablated surfaces are more active with lower polarization resistances and higher corrosion current, which suggests that the laser-ablated surfaces are more susceptible to corrosion, the increased roughness by laser ablation plays a crucial role in the improved corrosion resistance of laser-ablated adhesively bonded joints, as rough surfaces effectively retard the diffusion of corrosive solution.

表面处理已广泛应用于多种金属材料，以改变其物理化学性质并提高粘合接头的强度和耐用性。在可用的表面处理方法中，激光烧蚀具有效率高，环境友好和易于工业化的优点。在这项工作中，激光烧蚀的原理及其对金属材料的物理化学性质的影响进行了综述。综述并讨论了由激光烧蚀的金属材料制成的胶合接头的改进的胶合强度和耐腐蚀性的机理。激光烧蚀的粘接接头的粘接强度随金属被粘物表面的粗糙度和润湿性的增加而增加，仅当粘合剂能够充分润湿激光烧蚀的表面以在粘结界面形成机械互锁时，表面粗糙度才有助于提高接合强度。尽管激光烧蚀的表面更具活性，但极化电阻较低，腐蚀电流较高，这表明激光烧蚀的表面更容易受到腐蚀，但是激光烧蚀所增加的粗糙度在提高激光烧蚀的耐蚀性方面起着至关重要的作用。烧蚀的粘结接头，因为粗糙的表面有效地阻止了腐蚀性溶液的扩散。
