Special Issue Information

Dear Colleagues,

Laser-assisted manufacturing has revolutionized modern production by offering precision, flexibility, and efficiency in material processing. These processes leverage laser technology for cutting, welding, additive manufacturing, surface treatment, and hybrid machining, enabling enhanced control over microstructural evolution, surface integrity, and mechanical properties. As industries continue to push the boundaries of material performance and process optimization, advanced laser-based techniques play a pivotal role in sectors such as aerospace, automotive, medical devices, and energy.

This Special Issue of Journal of Manufacturing and Materials Processing (JMMP) aims to showcase the latest advancements in laser-assisted manufacturing, highlighting novel methodologies, process modeling, material interactions, and industrial applications. We welcome original research and review articles that address improvements in process efficiency, defect mitigation, sustainability, and integration with emerging technologies such as artificial intelligence and Industry 4.0.

We are interested in contributions focusing on topics such as the following:

  • Laser-based manufacturing;
  • Selective laser melting (SLM) and laser powder bed fusion (LPBF);
  • Laser cutting, welding, and drilling;
  • Hybrid and multi-energy laser-assisted processes;
  • Process monitoring and control in laser machining;
  • Laser–material interactions and thermal modeling;
  • Surface functionalization and microstructural evolution;
  • AI-driven process optimization and Industry 4.0 integration;
  • Applications in aerospace, automotive, biomedical, and energy industries;
  • Sustainability and energy efficiency in laser processing.

In mechanical engineering, interest in reliable and practicable technologies for nano- and microstructuring of tool surfaces is increasing. Femtosecond laser structuring offers a promising approach that combines high processing speeds with high precision. However, a knowledge gap remains regarding the optimal process parameters for achieving specific surface patterns on hot-work tool steel substrates. The current study aims to investigate the effects of laser scanning parameters on the formation of self-organized surface structures and the resulting topography and morphology. Therefore, samples were irradiated using a 300 fs laser with linearly polarized light (λ = 1030 nm). Scanning electron microscopy revealed four structure types: laser-induced periodic surface structures (LIPSSs), micrometric ripples, micro-crater structures, and pillared microstructures. The results for surface area and line roughness indicate that high laser pulse overlaps lower the strong ablation threshold more effectively than high scanning line overlaps, promoting the formation of pillared microstructures. For efficient ablation and increased surface roughness, higher pulse overlaps are therefore advantageous. In contrast, at low fluences, higher scanning line overlaps support a more homogeneous formation of nanostructures and reduce waviness. Full article

In this study, the corrosion performance and near-surface residual stress state of laser-welded Ti6Al4V/AA7075 dissimilar joints produced with a silver (Ag) interlayer are investigated. Potentiodynamic polarization, cyclic polarization, and electrochemical impedance spectroscopy (EIS) were carried out on Ti6Al4V base alloy (BA), AA7075 BA, and the fusion zone (FZ) containing the Ag interlayer. The Ag interlayer FZ exhibits an intermediate but clearly improved corrosion response compared with AA7075 BA, with a corrosion potential Ecorr ≈ 0.260 V, corrosion current density icorr ≈ 4.55 × 10−6 A cm−2, and polarization resistance Rp ≈ 7.08 kΩ cm2. EIS fitting further indicates a charge-transfer resistance of Rct ≈ 3.7 × 104 Ω cm2 and a moderate oxide film resistance, consistent with a more stable electrochemical interface than AA7075 BA in 3.5 wt.% NaCl. Additionally, the residual stress measurements reveal that the Ag interlayer joint develops a predominantly compressive residual stress field on both sides of the weld. This compressive state is beneficial for delaying pit-to-crack transition and enhancing durability under corrosive loading. A brief comparison with our previously published Ti6Al4V/AA7075 welds produced using a Cu interlayer under the same laser welding parameters and joint configuration as the present study shows that the Ag interlayer provides more favourable compressive residual stresses and a more noble, higher-resistance electrochemical response.
