“…In addition, there is significant thermal damage in the bottom morphology. These results are well with experimental results presented by Sugár et al In contrast, laser ablation‐induced thermal damage is highly reduced for the surface textures fabricated with a pulse duration of 15 ps (Figure e) and 400 fs (Figure f). Consequently, a reduction in the pulse duration leads to the generation of more homogeneous surface textures with minimum recast phenomena, smoother sidewalls as well as a highly reduced and almost negligible HAZ, which agrees well with previously published research work studies …”

Laser surface texturing is a powerful tool to fabricate functional surface textures, whereby their morphology and cross-sectional profile greatly depend on laser parameters such as pulse duration and fluence. In this work, the authors fabricate well-defined groove-like textures on stainless steel by laser surface texturing using different pulse durations ranging from nano-to femtoseconds, while keeping structural parameters such as depth and periodicity fairly constant. By doing so, the influence of the pulse duration on the resulting cross-sectional profile of the textures and its subsequent impact on the tribological response are assessed. Reciprocating ball-on-disk tests and computational fluid dynamic simulations with Abaqus are used to evaluate the tribological performance of the as-fabricated textures. Their results demonstrate that the use of laser pulses with different pulse durations induce changes in the resulting cross-sectional profiles with the formation of rims/bulges well as the occurrence of recast phenomena and debris accumulation for nanosecond laser pulses. Decreasing the pulse duration significantly reduces the heat affected zone and the thermal damage, as well as avoided the formation of rims/bulges. Reciprocating ball-on-disk tests demonstrated that the differences in the cross-sectional profiles have a significant influence on friction and wear behavior of the textured surfaces.

The morphological texturing of forming tool surfaces has a high potential to reduce friction and tool wear and also has an impact on the surface layers properties of formed material. In order to understand the effect of different types of tool textures, produced by nanosecond fibre laser, on the tribological conditions at the interface tool-formed material and on the integrity of formed part surface layers, the series of experimental investigations have been carried out. The coefficient of friction for different texture parameters (individual feature shape, including the depth profile of the cavities and orientation of the features relative to the material flow) was evaluated via a Ring Test and the surface layers integrity of the formed material (surface roughness and subsurface micro hardness) was also experimentally analysed. The results showed a positive effect of surface texturing on the friction coefficients and the strain hardening of test samples material. Application of surface texture consisting of dimple-like depressions arranged in radial layout contributed to the most significant friction reduction of about 40%. On the other hand, this surface texture contributed to the increase of surface roughness parameters, Ra parameter increased from 0.49 μm to 2.19 μm and the Rz parameter increased from 0.99 μm to 16.79 μm.

“…The microstructures can act as small traps for debris and behave as micro-reservoir for lubricant which reduces the friction [6]. LST has been successfully applied to various engineering materials like ceramic [7,8], metals [9,10], polymers [11]. This method has been successfully used in various engineering applications in the biomedical, tribology, coating domains.…”

For generating a texture or pattern on a work surface, one of the emerging processes is laser surface texturing (LST). It is an effective method for producing texture on a work surface. Literature shows that various lasers have been applied to generate textures on the surface of work materials. Recently, LST has shown tremendous potential in the field of biomedical applications. Applying the LST process, the efficacy of the biomaterial has been drastically improved. This paper presents an in-depth review of laser surface texturing for biomedical applications. The effect of LST on important biomaterial has been thoroughly studied; it was found that LST has extreme potential for surface modification of biomaterial and can be utilized for biomedical applications.
