“…Mixing concave and convex textures might be a way to give the resulted texture additional features. Segu et al [75] recently developed a combined texture made by a circular dimple and a wavy groove, resulting in an improved friction coefficient. These beneficial effects might be explained by the largest combined converging wedge and the smallest separation, which were triggered by different texture shapes and act as oil reservoirs.…”

“…The texture size (depth and diameter) has a considerable effect on the tribological properties by storing the lubricants, trapping wear debris, avoiding the oil layer rupture, and enhancing the load bearing capacity [75]. The impact of groove size on the enhancement of tribological properties under sand-oil lubrication was explored by Dongya et al [66].…”

“…The load bearing capability of the surface texture decreases as the area density rises, lowering the tribological features [61]. Recently, four different densities of 10%, 15%, 20%, and 25% with corresponding aspect ratios of 0.16 and 10% (texture 1), 0.16 and 15% (texture 2), 0.16 and 20% (texture 3), 0.16 and 25% (texture 4), and 0.08 and 10% (texture 5) were investigated [75]. The reference sample T6 and the simple texture samples T7 (circles/dimples) and T8 (sine wave channels) were also tested and compared.…”

“…The effect of the arrangements can be improved further with the sliding direction. Some scientists [11,68,75], found that dimples with a distribution perpendicular to the reciprocating motion resulted in the production of a thicker film and a lower friction than those parallel to the sliding direction. In addition, for texture shapes such as the triangle or chevron, the orientation of the patterns to the sliding direction was significant in decreasing the friction when the side border perpendicular to the sliding motion first approached the region of contact [11].…”

“…In addition, for texture shapes such as the triangle or chevron, the orientation of the patterns to the sliding direction was significant in decreasing the friction when the side border perpendicular to the sliding motion first approached the region of contact [11]. However, the effect of the sliding direction on orientations may change [75]. Perpendicular grooves do not provide substantial tribological enhancements due to their huge transversal dimensions, and, when compared to untextured surfaces, parallel grooves reduced the performance of curved surfaces by increasing contact of the surfaces and the friction [3].…”

Surface texture is regarded as a promising solution for enhancing the tribological features of industrial materials due to its outstanding benefits, such as minimization of the contact area, enhancement of the load bearing capacity, storage of the lubricant, and management of the transition between lubrication regimes. Surface texture can be processed under either liquid or gas conditions. As compared to laser ablation in air, employing liquids or other gases as ablation media provides high accuracy and uniformity by limiting the heat-affected zone (HAZ) and other undesired defects to a large extent, as well as high crater structural features. In addition, the synergistic use of different liquid, solid, and additive lubricants with surface roughness recently demonstrated excellent performance. Therefore, surface texture helps to improve the tribological characteristics of a material. This paper reviews the design methodologies and applications of surface texture, emphasizing the proper selection of the appropriate laser parameters and ambient conditions for the best texture quality and functionality. Recent texture geometric design features to improve the film thickness and the self-lubricating system are presented. The ablation environment is explored using various media. The interaction between the lubricants’ types and surface textures is explored based on the operating conditions. Furthermore, surface texture applications using superhydrophobic surfaces, anti-drag, and vibration and noise friction are discussed. We hope that this review plays an enlightening role in follow-up research on laser surface texture.

In recent years, slippery liquid infused porous surfaces (SLIPS) renowned for their exceptional liquid repellency and anti‐fouling properties, have garnered considerable attention. However, the instability of both structural integrity and the oil film severely restricts their practical applications. This study is inspired by superwetting biological surfaces, such as fish scales, seashells, and Nepenthes, to design and fabricate a multiplex biomimetic and robust lubricant‐infused textured surface (LITMS) using laser‐coating composite processing technology. The influence of morphological structure and chemical composition on oil stability, wettability, and lubricating properties are systematically investigated. The LITMS exhibits remarkable repellency toward multiphase materials, including liquids, ice crystals, and solids, demonstrating exceptional omniphobicity, anti‐icing, and anti‐friction properties. Thus, this preparation strategy and construction methodology for SLIPS provide new insights into interfacial phenomena and promote advancements in applications for engineering material protection and machinery lubrication.
