“…From the experimental results, both ring structure and microcrack could be tailored (pre-defined) to a certain extent in order to improve the adhesive bonding of aluminum alloys. One year later, a research group led by Geiger [63] fabricated microstructures on ceramic surfaces by excimer laser radiation to improve the tribological properties under hydrodynamic and elastohydrodynamic sliding conditions (refer to Fig. 11).…”

This review gives a concise introduction to the state-of-art techniques used for surface texturing, e.g., wet etching, plasma etching, laser surface texturing (LST), 3D printing, etc. In order to fabricate deterministic textures with the desired geometric structures and scales, the innovative texturing technologies are developed and extended. Such texturing technology is an emerging frontier with revolutionary impact in industrial and scientific fields. With the help of the latest fabrication technologies, surface textures are scaling down and more complex deterministic patterns may be fabricated with desired functions, e.g., lotus effect (hydrophobic), gecko feet (adhesive), haptic tactile, etc. The objective of this review is to explore the surface texturing technology and its contributions to the applications.

“…In this case, the depth of the cavities was about 10 µm. With minor exceptions and limitations, laser texturing has been found benefi cial for both steel [4][5][6][7] and ceramic [8][9][10][11][12] surfaces.…”

Lubrication improvement and friction reduction of DLC‐coated sliding surfaces by in‐process structuring and post polishing

The paper describes an experimental investigation on the infl uence of the surface roughness of diamond-like hard carbon (DLC) coatings on the friction and wear in sliding contact against steel under conditions of starving lubrication. Experimental studies employed a reciprocating ball-on-fl at tribometer in two different modes of operation. The study showed a microlubrication effect in terms of lubrication assistance achieved by microscopic cavities in the topography of a DLC coating and good sliding behaviour even in the case of starving oil lubrication. Post-process polishing of the coated surfaces was adopted for eliminating unnecessary friction losses due to asperity interactions and micro-abrasive wear.

“…Different texturing elements, e.g. dimples [5,6,7], crossed and parallel microchannels [8,9], triangles [10], squares [11], as well as other more complex shapes [12,13], have been studied worldwide for tailor tribological performance, however, the most common texturing features are still circular dimple-like depressions, because of…”

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.
