“…A short laser pulse ablation is melt-free with a minimal thermal impact, no visible material pile-up, and no convex shape on the ablation edge [41,42]. As a result, femtosecond pulses have more advantageous effects on the HAZ compared to nanosecond, picosecond, and millisecond pulses [37,38].…”

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.

Taking CuPb20Sn5 as the research object, the CuPb20Sn5/Carbon steel bimetallic sample was prepared by the solid-liquid compound method, and the relationship between the microstructure and friction properties of the bimetallic CuPb20Sn5 layer. The results show that the Cu3P and δ (Cu31Sn8) phases in CuPb20Sn5 are distributed in the α-Cu to improve the wear resistance of the alloy. The friction coefficient fluctuates in the range of 0.057~0.093, when the load was 150 N-350 N. When the speed exceeds 3.86 m/s, as the load increases, the friction coefficient first increases and then decreases, and the wear rate increases. When the load was less than 250 N, the wear surface of CuPb20Sn5 was smooth, and the material was basically free of wear. When the load was 300 N, the friction coefficient reaches the lowest point, and the third body friction layer was formed in CuPb20Sn5 layer, and the wear mechanism was slight adhesive wear. When the load was greater than 300 N, Pb will fall off the CuPb20Sn5 surface, and the friction coefficient increase, causing abrasive wear.

“…[ 1,2 ] However, the main disadvantages limiting the widespread commercial use of these materials is their poor corrosion resistance caused by the high chemical reactivity of magnesium as well as the poor wear resistance. [ 3–5 ] Therefore, surface protection of these materials via microarc oxidation, [ 6 ] femtosecond laser, [ 7 ] electrodeposition, [ 8 ] plasma electrolytical oxidation, [ 9 ] plasma jet [ 10 ] and so forth, is an attractive strategy for improving their performance and longevity. However, these technical solutions are complex, cumbersome, inefficient and hazardous to the environment.…”
