Abstract

Utilizing ultrasonic vibration to modify laser path morphology and reconstruct surface microstructure. The impact of ultrasonic vibration on laser processing of functional surfaces has been thoroughly investigated, Micro and nanostructures were generated on a 1 mm thick aluminum substrate using an ultrasonic-assisted nanosecond pulse laser with a grid pattern scanning method, The input variables of the investigated process include laser scanning speed, ultrasonic vibration amplitude, and ultrasonic vibration frequency. The results showed that the ravine width of laser ablation increased by 50 % with the application of ultrasonic vibration, which caused the efficiency of ultrasonic assisted laser processing (UALP) increased by 7.19 % compared with normal laser processing (NLP). The addition of ultrasonic vibration resulted in elongated laser craters and recast layers oriented in the direction of the vibration, forming elliptical shapes. and became "elliptical", which narrowed the distance between the recast layers and made the surface structure more compact. At the same time, the ultrasonic vibration made the melted material splash and increased the surface roughness of the sample, which made the aluminum plate had superhydrophobic with a maximum contact angle of 154.92º.

超声振动改善激光烧蚀铝的表面形貌和润湿性

利用超声振动改变激光路径形态，重建表面微观结构。研究了超声振动对功能表面激光加工的影响，利用超声辅助纳秒脉冲激光器和网格扫描方法在1 mm厚的铝基板上生成微纳结构，研究过程的输入变量包括激光扫描速度、超声振动幅值和超声振动频率。结果表明：在超声振动作用下，激光烧蚀沟宽度增大50%，超声辅助激光加工效率比普通激光加工效率提高7.19%；超声振动的加入使激光弹坑呈细长状，并沿振动方向重铸层，形成椭圆形状。并变成“椭圆形”，从而缩小了重铸层之间的距离，使表面结构更加紧凑。同时，超声振动使熔化的材料飞溅，使样品表面粗糙度增加，使铝板具有超疏水性，最大接触角为154.92º。

期刊介绍： Optics and Lasers in Engineering aims at providing an international forum for the interchange of information on the development of optical techniques and laser technology in engineering. Emphasis is placed on contributions targeted at the practical use of methods and devices, the development and enhancement of solutions and new theoretical concepts for experimental methods. Optics and Lasers in Engineering reflects the main areas in which optical methods are being used and developed for an engineering environment. Manuscripts should offer clear evidence of novelty and significance. Papers focusing on parameter optimization or computational issues are not suitable. Similarly, papers focussed on an application rather than the optical method fall outside the journal''s scope. The scope of the journal is defined to include the following: -Optical Metrology- Optical Methods for 3D visualization and virtual engineering- Optical Techniques for Microsystems- Imaging, Microscopy and Adaptive Optics- Computational Imaging- Laser methods in manufacturing- Integrated optical and photonic sensors- Optics and Photonics in Life Science- Hyperspectral and spectroscopic methods- Infrared and Terahertz techniques
