Morphology modelling and validation in nanosecond pulsed laser ablation of metallic materials

Yan Wang et al.

Summary: A simple and novel model for nanosecond pulsed laser processing based on heat transfer and geometrical mathematics is proposed in this paper, and its feasibility is validated through experiments. The model predicts the shape of the recast layer on pulsed laser ablated metal surfaces, and guides the preparation of surface functionalities and the selection of process parameters for microstructure machining.

Numerical and experimental analysis for morphology evolution of 6061 aluminum alloy during nanosecond pulsed laser cleaning

Lingyu Guo et al.

Summary: This study established a 3D heat transfer and flow coupling model of laser cleaning for aluminum alloy oxide film and analyzed the dynamic evolution of surface morphology with different laser power. The results showed that the splash phenomenon is mainly influenced by the combined effects of recoil pressure, surface tension, and gravity.

Tailored surface textures to increase friction-A review

Henara L. Costa et al.

Summary: Surface textures with micro-scale feature dimensions have the potential to enhance frictional performance and intentionally increase friction in various applications. This review presents the state-of-the-art in textured surfaces for high-friction purposes, summarizing recent trends in laser surface texturing and discussing the potential of surface textures in different applications. The involved mechanisms responsible for friction increase are emphasized, and current shortcomings and future research directions are addressed to highlight the great potential of (laser-based) surface texturing methods for innovations in surface engineering.

Numerical micro-texture optimization for lubricated contacts-A critical discussion

Max Marian et al.

Summary: Despite the amount of research conducted, the optimization strategies for micro-textures in lubricated tribo-contacts are still not well-established. Numerical approaches have the potential to design and optimize micro-textures to reduce friction and wear, contributing to improved energy efficiency and sustainability.

Effects of Laser Surface Texturing and Lubrication on the Vibrational and Tribological Performance of Sliding Contact

Shunchu Liu et al.

Summary: The study shows that laser surface textures can reduce the coefficients of friction, enhance wear resistance, and improve the dynamical performance of frictional surfaces. The surface with micro circular dimples in diameter of 150 mu m or textured area density of 25% has the best tribological and dynamical performance. Adding graphene to the lubrication oil effectively reduces frictional vibrations and noise, and surface textures enhance the frictional noise reduction performance of lubrication.

Surface modeling and component analysis of picosecond laser ablation of CVD diamond

Bo Yan et al.

Summary: This study investigated the optimization of CVDD surface irradiation via picosecond laser and analyzed the effects of laser parameters on the surface morphology, roughness, removal depth, and components of CVDD. The results showed that the trend in changes of roughness and removal depth based on theoretical model was similar to experimental results, with average relative errors of 9.6% and 16.6% respectively. Additionally, the study found that the removal depth of CVDD surface decreased with increasing scanning speed and filling pitch, but increased with the increase in average laser power. The reduction of overlapping area of pulse spot could mitigate the exacerbation of sp2 hybrid amorphous carbon defects.
