Special Issue Information

Dear Colleagues,

Advanced micro/nano-, cutting/laser-based machining technologies, such as micromachining of complex parts and geometric structures and features; structuring and texturing of functional, optical, and tooling surfaces, are the key technologies for creating new and/or enhancing existing values of functional parts and products. These surface engineering technologies exhibit significant advantages over conventional processes in terms of process reconfigurability, accuracy, precision, surface quality, versatility, processing time and cost, and minimal environmental impact. In addition, nano/micromachining technologies can be seamlessly integrated with novel material additive processes and systems for surface formation and topography enhancement and functionalization. 

The aim of this Special Issue is to cover advanced developments, functionalities, and applications in functional microstructures and textures produced using micro/nano-, cutting/laser-based machining technologies. It also seeks to highlight research on system and part design; process and performance modelling; microfabrication; and performance evaluation of the micromachining process and/or functional surfaces and their precision, accuracy, quality, and efficiency improvement for a wide range of applications related (but not limited to) the control of wettability, friction, optical appearance, light guiding, corrosion, hydro- and aero-dynamics, and biofouling resistance. 

We invite leading experts and researchers in this field to submit original research papers, comprehensive reviews, and communications addressing any of the topics mentioned below:

  • Functional surfaces and micro-/nanostructures for enhanced wettability, friction, hydro-/aerodynamics, light guiding, optical holography, self-cleaning, drag, biofouling resistance, solar light trapping, boiling, water condensation, adhesion, alumophobicity, etc.;
  • Functional surfaces and micro-optics for advanced optical performance (e.g., illumination, retroreflection, holography, light guiding, diffraction, sensing, etc.) and controlled visual appearance (e.g., brand recognition, artistic effects, etc.)
  • Cutting-based micro/nanomachining including single-point cutting, milling, vibration-assisted cutting, fast/slow tool servo and other advanced technologies for microfabrication, structuring, texturing, polishing, etc.;
  • Laser-based micro/nanomachining including ablation, remelting, microcladding, and other advanced technologies for structuring, texturing, polishing, remelting, alloying, etc.

Additive manufacturing (AM) is an advanced manufacturing method that produces objects by sequential layering. Material extrusion AM (MEAM) with continuous-fibre reinforcement is becoming more widely used in naval structures, which are exposed to the marine environment. However, the water diffusion process and the effect of water ageing on the mechanical performance of AM materials are not yet well understood because of their complex internal structure, caused by defects generated during manufacturing. Current research on diffusion is mostly based on experimental methods for conventionally manufactured materials without considering AM-induced defects. The objective of this study is to explore how the defects inherent to MEAM affect water diffusion in a composite material by the capillary effect. Results from a numerical study of capillary flow in MEAM polymer are applied as a boundary condition in the subsequent finite-element analysis. The study illustrates that flow in the capillary reaches the steady state quicker compared to the saturation time in the matrix, predicted by Fick’s diffusion equation. It is demonstrated that the capillary effect can significantly affect the water diffusion in MEAM parts and reduce the saturation time to one-third compared to the case without accounting for this effect.
