Special Issue Information

Dear Colleagues,

Laser processing is a groundbreaking technique that is revolutionizing advanced manufacturing across a wide range of materials. With its notable advantages of high efficiency, superior quality, automation, and customization, laser processing techniques have found extensive applications in various industrial sectors, including aerospace, energy, transportation, and healthcare. However, the demands of manufacturing technology in these industries are constantly evolving, becoming more complex and stringent. It is evident that further research is necessary to enhance our understanding of process physics, to optimize processes, and to develop novel applications.

This Special Issue aims to create a platform for showcasing cutting-edge advancements, inspiring new developments and promoting the applications of laser material processing. We welcome both original research papers and reviews from scientists, researchers, engineers, and experts in this field. Topics of interest include the following areas:

  • Laser processing and additive manufacturing;
  • Laser machining, including cutting/drilling/texturing;
  • Laser forming, including bending/rapid prototyping/coloring/deposition;
  • Laser joining, including laser welding/brazing/soldering/sintering;
  • Laser–matter interaction in material processing;
  • Laser-based surface engineering.

In this study, silicon carbide nanoparticles (NPs) were produced via pulsed laser ablation in liquid, aiming to investigate the influence of processing parameters on the properties of the resultant NPs and their applicability for inkjet printing. The results revealed an increase in NP concentration with increasing laser power, but the maximal absorbance in the case of 0.743 and 1.505 W is lower than that for 1.282 W laser. Dynamic light scattering was employed to determine the size distribution of the NPs, demonstrating a range of 89 to 155 nm in diameter. Notably, an inverse relationship was established between increasing laser scanning speed and pulse repetition rate (PRR) and the mean size of the NPs. Higher PRR and laser power exhibited an augmentation in the concentration of NPs. Conversely, an increase in scanning speed resulted in a reduction in NP concentration. Based on FTIR, data formation of SiC NPs based on the target material is the most dominant behavior observed followed by an amount of oxidation of the NPs. Examination of the resulting NPs through field emission scanning electron microscopy equipped with energy-dispersive X-ray analysis (EDX) unveiled a predominantly spherical morphology, accompanied by particle agglomeration in some cases, and the elemental composition showed silicon, carbon, and some oxygen present in the resulting NPs. Furthermore, the modulation of colloidal solution viscosity was explored by incorporating glycerol, yielding a maximal viscosity of 10.95 mPa·s. Full article
