“…Laser surface texturing (LST) was implemented with a laser micromachining system for replicating topographic features of a honing stone in a WC-base cemented carbide grade, commonly employed for making tools [289]. The laser-patterned cemented carbide tools could be used in honing process, as alternative to conventional honing stones.…”

The reach of tribology has expanded in diverse fields and tribology related research activities have seen immense growth during the last decade. This review takes stock of the recent advances in research pertaining to different aspects of tribology within the last 2 to 3 years. Different aspects of tribology that have been reviewed including lubrication, wear and surface engineering, biotribology, high temperature tribology, and computational tribology. This review attempts to highlight recent research and also presents future outlook pertaining to these aspects. It may however be noted that there are limitations of this review. One of the most important of these is that tribology being a highly multidisciplinary field, the research results are widely spread across various disciplines and there can be omissions because of this. Secondly, the topics dealt with in the field of tribology include only some of the salient topics (such as lubrication, wear, surface engineering, biotribology, high temperature tribology, and computational tribology) but there are many more aspects of tribology that have not been covered in this review. Despite these limitations it is hoped that such a review will bring the most recent salient research in focus and will be beneficial for the growing community of tribology researchers.

“…Recently, the authors of this study have successfully sculptured hexagonal pyramids with defined geometry, similar to CBN abrasive particles, on a cemented carbide grade by using an ultra-short pulse laser [10,11]. Compared to a CBN honing stone, these pyramids achieved similar effectiveness in material removal, as assessed in preliminary abrasive machining tests.…”

A nanosecond laser combined with a 2-axis reflection control unit is used to shape polygonal pyramids with defined geometry on a specific cemented carbide grade. In total, 12 different surface patterns have been fabricated, including four pyramid shapes, i.e. triangle, square, hexagon and octagon, and three lateral side angles, i.e. 30°, 45° and 60°. Characterization of the geometrical features shows satisfactory agreement between produced patterns and aimed ones. The precision is improved when the number of polygon sides and/or both side and slope angles increase. Side effects, such as re-deposition, cracks and pores, were discerned through scanning electron microscopy inspection. They become less obvious when the polygon side length or side angle increases, as the material melting becomes less important. Based on the observations, a borderline curve can be plotted for describing the production capability of such surface patterns on cemented carbides using the laser technology.

“…Lickschat et al [ 87 ], when investigating ultrashort pulse durations, found the ablation threshold of WC decreased from 0.4 J/cm 2 to 0.26 J/cm 2 as the pulse duration decreased from 10 ps to 0.2 ps, respectively. Fang et al [ 88 ] using green laser light (532 nm) also demonstrated a decrease in ablation threshold on WC-CoNi from 2.5 J/cm 2 to 0.5 J/cm 2 when the pulse duration regime was changed from nanosecond to picosecond. Figure 12 is a comparison of the damage and ablation fluence thresholds in different materials based on a pulse duration of 150 fs, 800 nm, 1 kHz, using the investigations of Dumutri et al [ 60 ], Zheng et al [ 89 ], and Denkena et al [ 90 ].…”

“…Surfaces are often smoother but shallower, requiring multiple laser passes. At fluences much higher than the threshold, phase explosion and plasma heating (superheated liquid) dominate, giving a material removal rate of about 100 nm per pulse [ 44 ] (or 37.5 mm 3 /min [ 88 ]). As a result, the higher fluence will cause deeper features in fewer passes, which is very efficient ( Figure 13 a) but often matched with an increased surface roughness.…”

Polycrystalline diamonds, polycrystalline cubic boron nitrides and tungsten carbides are considered difficult to process due to their superior mechanical (hardness, toughness) and wear properties. This paper aims to review the recent progress in the use of lasers to texture hard and ultra-hard materials to a high and reproducible quality. The effect of wavelength, beam type, pulse duration, fluence, and scanning speed is extensively reviewed, and the resulting laser mechanisms, induced damage, surface integrity, and existing challenges discussed. The cutting performance of different textures in real applications is examined, and the key influence of texture size, texture geometry, area ratio, area density, orientation, and solid lubricants is highlighted. Pulsed laser ablation (PLA) is an established method for surface texturing. Defects include melt debris, unwanted allotropic phase transitions, recast layer, porosity, and cracking, leading to non-uniform mechanical properties and surface roughness in fabricated textures. An evaluation of the main laser parameters indicates that shorter pulse durations (ns—fs), fluences greater than the ablation threshold, and optimised multi-pass scanning speeds can deliver sufficient energy to create textures to the required depth and profile with minimal defects. Surface texturing improves the tribological performance of cutting tools in dry conditions, reducing coefficient of friction (COF), cutting forces, wear, machining temperature, and adhesion. It is evident that cutting conditions (feed speed, workpiece material) have a primary role in the performance of textured tools. The identified gaps in laser surface texturing and texture performance are detailed to provide future trends and research directions in the field.
