Special Issue Information

Dear Colleagues,

Laser surface modification has become a promising technique for the fabrication of functional metallic surfaces due to its advantages of process flexibility, ease of automation and environmental friendliness. By employing laser treatments, the key surface properties of metallic materials can be modified, including the surface microstructure, surface roughness, surface wettability, reflectance, mechanical properties, as well as corrosion and abrasion resistance. In addition, techniques for the characterization of these surface properties are also of great importance. Laser-engineered surfaces are necessary for various applications in many industrial sectors, such as the aeronautical, automotive, energy, or biomedical sectors. However, as an emerging surface processing technology, there remain many aspects to be further explored, including the interaction mechanism between the laser beam and materials, novel techniques for the fabrication of functional structures, innovative techniques for the characterization of surface functionalities and the development of high-efficient and low-cost laser-based processes.

The aim of this Special Issue is to cover the latest developments in laser surface modification techniques for the design, modelling, fabrication and characterization of metallic functional surfaces and surface property modification; this is with regard to the control of the microstructure, wettability, optical properties, corrosion, abrasion, and mechanical properties. This Special Issue welcomes the submission of full research papers, comprehensive reviews and communications that address the topics included in the keywords below. We hope to synergize the innovative research conducted by world-class investigators and leading experts in this research area.

Zinc germanium phosphide (ZGP) crystals have garnered significant attention for their nonlinear properties, making them good candidates for powerful mid-IR optical parametric oscillators and second-harmonic generators. A ZnGeP2 single crystal was treated by deep magnetorheological processing (MRP) until an Angstrom level of roughness. The studies presented in this article are devoted to the experimental evaluation of the influence of deep removal (up to 150 μm) from the surface of a ZnGeP2 single crystal by magnetorheological polishing on the parameters of optical breakdown. It was shown that the dependence of the ZnGeP2 laser-induced damage threshold on MRP depth is a smooth monotonically decreasing logarithmic function. The obtained logarithmic dependence indicates the thermal nature of optical breakdown and the dependence of the ZnGeP2 laser-induced damage threshold on the concentration of surface absorbing defects.

Surface texturing, which has recently garnered increased attention, involves modifying the surface texture of materials to enhance their tribology. Various methods have been developed for surface texturing. Laser surface texturing (LST) has attracted considerable interest because of its excellent texturing accuracy, controllability, and flexibility. It improves surface wettability properties and increases the wear resistance of materials while reducing the coefficient of friction. Herein, we present an overview of the underlying mechanisms of interactions between short-pulsed lasers and materials. In addition, we review published studies on the effects of LST on surface properties, including surface roughness, wettability, friction, and wear resistance. We believe that this review will provide valuable insights into the recent advances in surface property enhancement through LST, which exhibits potential for various applications. Full article
