Summary: Despite similar mechanical properties between snake skin and epoxy resin, strong differences in frictional and wear mechanisms were revealed. Snake skin exhibited a considerably lower and stable frictional coefficient over several sliding cycles. Reduction of stick-slip behavior and wear mechanism changes were observed by analyzing friction coefficient variation in forward and reverse motion.

Summary: Laser texturing is a common method used to customize the tribological performance of PVD coatings. Two strategies can be employed: laser texturing of the substrates prior to coating deposition, or laser texturing of the already deposited coating. The effect of structural changes caused by laser ablation on friction performance is not well studied.

Summary: The study found that under different sliding conditions, dimples defined by nanosecond laser exhibited the lowest steady-state coefficient of friction, while in Hank's solution, lines and crosshatching showed better frictional characteristics after running-in and the removal of bulges around the laser textures. In terms of wear resistance, low-density lines pattern and particularly dimples were the most promising in contact situations likely to occur during starved/dry-lubrication conditions.

Summary: In this study, dimples created on an ASTM F-1537 cobalt alloy surface using ns-pulse laser at different processing parameters were found to improve wear resistance. Surface characteristics were evaluated using various techniques, showing that the texturized samples had a lower wear rate compared to untreated samples, which was attributed to the variation in dimple diameter and depth.

Summary: This study demonstrates that creating anisotropic microstructures on steel surfaces using laser surface texturing (LST) and depositing thin molybdenum nitride coatings through high-power impulse magnetron sputtering (HiPIMS) can significantly improve the surface wear resistance. The orientation of the structures and wear track have a substantial impact on friction and wear, with the main effect being the removal of abrasion particles from the mechanical contact.

Summary: The study fabricated a series of Ag coatings with different micro-dimples on copper surfaces using laser surface texturing (LST) and magnetron sputtering and lubricated them with multilayer graphene grease (MGLG). It was found that the textured Ag coatings showed improved tribological and electrical properties under MGLG lubrication compared to non-textured coatings. The synergistic effect of LST and MGLG was believed to contribute to these excellent performances.

Summary: Composite peening is a novel process that introduces ceramic blasting particles into the surface of substrates, with blasting particles penetrating to a depth of several micrometers depending on process parameters. Analysis using scanning electron microscopy and transmission electron microscopy reveals a severely deformed, nanocrystalline ceramic layer consisting of fragmented blasting particles. X-ray diffraction further confirms the presence of this unique microstructure.

Summary: Tribochemical reactions in copper and its oxides during mild tribological loading and dry sliding were investigated. Oxides were found to reduce the coefficient of friction due to an increase in hardness. The reduction of copper oxide to metallic copper was observed, indicating the potential for enhanced tribological properties through a better understanding of tribo-oxidation.

Summary: This study investigated the plasticity of single crystal films bonded to a rigid substrate under sliding by rigid sinusoid-shaped asperity using two-dimensional discrete dislocation plasticity (DDP) calculations. Results showed that microstructural changes observed during sliding tests were likely caused by localized lattice rotation bands formed by the activity of dislocations. The depth and magnitude of the lattice rotation bands were found to be related to the sliding distance and contact size.

Summary: While modifying surface contacts can reduce friction, it is challenging to achieve consistent friction behavior in real-life experiments and virtual simulations. This work establishes a digital twin of a pin-on-disk tribometer using real-life measurements and calibrates it to accurately represent the friction behavior. It also uses the Hersey number to validate the method for different dynamic viscosities.
