“…Polymers absorb the laser energy in a non-linear manner compared to metals. Ablation includes both vaporization and melt ejection from the focal area [32]. If the energy of an incident laser beam is less than the ionization potential of the polymer-bound valence electrons, vaporization will not occur.…”

Micro- and nanoscale structures produced on surfaces of metals, polymers, ceramics, and glasses have many important applications in different fields such as engineering, medical, biological, etc. Laser ablation using ultrashort pulses has become the prominent technique for generating different surface structures for various functional applications. Ultrashort laser ablation proved to be ideal for producing structures with dimensions down to the nanometre scale. In comparison to other texturing techniques employed to create micro/nano features such as electrochemical machining, micro-milling, ion-beam etching, hot embossing, lithography, and mechanical texturing, ultrashort laser ablation produces high-quality surfaces at low cost in a one-step non-contact process. Advantageous characteristics of polymers such as high strength-to-weight ratio, non-corrosive nature, and high electrical and thermal resistance, have made polymers the preferred choice compared to other materials (e.g., steel, aluminium, titanium) in several fields of application. As a result, laser ablation of polymers has been of great interest for many researchers. This paper reviews the current state-of-the art research and recent progress in laser ablation of polymers starting from laser-material interaction, polymer properties influenced by laser, laser texturing methods, and achievable surface functionalities such as adhesion, friction, self-cleaning, and hydrophilicity on commonly used polymeric materials. It also highlights the capabilities and drawbacks of various micro-texturing techniques while identifying texture geometries that can be generated with these techniques. In general, the objective of this work is to present a thorough review on laser ablation and laser surface modification of a variety of industrially used polymers. Since direct laser interference patterning is an emerging area, considerable attention is given to this technique with the aim of forming a basis for follow-up research that could pave the way for potential technological ideas and optimization towards obtaining complex high-resolution features for future novel applications.

“…Some theoretical and experimental studies on the tribological effects of surface texturing show a reduction of friction with textured surfaces due to the effect of microcavities acting as lubricant reservoirs, 10,11 the enhancement of lubricant entrainment, and increase of load‐carrying‐capacity (LCC) under hydrodynamic lubrication, 9 the reduction of adhesion 12 and the effect of cavities acting as wear particle traps 4 . On the other hand, surface texturing can also be used as a mean for increasing friction.…”

The following theoretical and experimental work presents a study on the influence of texture parameters on the tribological performance of dimpled steel surfaces. Different texture parameters were selected through hydrodynamic lubrication modeling based on the two‐dimensional Reynolds equation and literature search. For the experimental work, microscopic spherical cavities (i.e., dimples) were created by laser on 25 mm steel discs. The textured specimens were tested in a unidirectional sliding line‐contact block‐on‐ring set‐up at different rotational speeds. The experiments showed that the area‐density‐ratio, dimple‐depth, and dimple‐diameter can significantly affect the tribological performance of steel surfaces. Specimens containing dimples with lower depth, lower area‐density‐ratio, and smaller diameters, exhibited significant improvements over a smooth steel surface. The most remarkable achievement was a 28.6% friction reduction at 20 RPM and an overall improvement of 13% considering all speeds.

“…In the field of tribology, a concept of micro texture is put forward. The definition of micro texture technology is to use certain processing methods to manufacture craters, grooves, or protrusions on the friction pair surface to improve tribological properties [14]. At present, laser processing technology, electron beam processing technology, LIGA (Lithographie, Galvanoformung, Abformung) technology, micro EDM (electrical discharge machining) technology, and micro turning technology are widely used to process micro textures on the cutting tool [15].…”

Titanium alloys are widely used in various fields, but their machinability is poor because the chip would easily adhere to the tool surface during cutting, causing poor surface quality and tool wear. To improve the cutting performance of titanium alloy Ti-6Al-4V, experiments were conducted to investigate the effect of micro textured tool on the cutting performances. The cemented carbide tools whose rake faces were machined with line, rhombic, and sinusoidal groove textures with 10% area occupancy rates were adopted as the cutting tools. The effects of cutting depth and cutting speed on feed force and main cutting force were discussed based on experimental results. The results show that the cutting force produced by textured tools is less than that produced by non-textured tools. Under different cutting parameters, the best cutting performance can be obtained by using sinusoidal textured tools among the four types of tools. The wear of micro textured tools is significantly lower than that of non-textured tools, due to a continuous lubrication film between the chip and the rake face of the tool that can be produced because the micro texture can store and replenish lubricant. The surface roughness obtained using the textured tool is better than that using the non-textured tool. The surface roughness Ra can be reduced by 35.89% when using sinusoidal textured tools. This study is helpful for further improving the cutting performance of cemented carbide tools on titanium alloy and prolonging tool life.
