摘　　要：利用纳秒脉冲激光器对316不锈钢表面进行激光毛化处理,研究激光毛化后材料表面形貌对电子标签粘接性能的影响。通过微机控制万能试验机对粘接结合力进行测量,研究激光毛化对材料表面形貌及粘接性能的影响规律,确定最佳激光毛化工艺参数。激光毛化可有效地提高材料表面粗糙度及接触面积,在最佳激光毛化工艺(激光功率200 W,扫描速度4 050 mm/s,重复频率50 kHz,脉冲宽度270 ns,填充线间距0.081 mm)下,激光毛化后材料表面的粗糙度较未处理前的0.024μm提升到2.406μm;激光毛化后粘接结合力为48.5 N,较未处理的粘接结合力18.2 N提高了166%。The surface of 316 stainless steel was treated by laser texturing with a nanosecond pulse laser to study the effect of surface morphology on the adhesive properties of electronic labels.The adhesion force was measured by microcomputer controlled universal testing machine.The influence of laser texturing on the surface morphology and adhesion properties of materials was studied,and the optimal laser texturing process parameters were determined.Laser texturing can effectively improve the surface roughness and contact area of the material.When the best laser texturing process is 20o W laser power,scanning speed is 4050 mm/s,repetition frequency is 50 kHz,pulse width is 270 ns,and flling line spacing is 0.081 mm,the surface roughness of the material after laser texturing is 0.024 higher than that before the treatmentμm raised to 2.406μm.After laser texturing,the adhesive strength is 48.5 N,which is 166%higher than that of untreated adhesive strength of 18.2 N.
