Data-driven approaches leverage large-scale datasets to extract effective design features via machine learning algorithms. These features are then utilized to optimize surface textures, ensuring they meet specific functional requirements. The model-driven approach is based on physical models and combines AI technology to perform parameter optimization and simulation to ensure the physical rationality of the design. By combining the advantages of data-driven and model-driven approaches, the data and model hybrid approach achieves a more efficient and accurate design process. In addition, the design of AI-aided surface textures for tribology, fluid dynamics and drag reduction, and biomedical applications is presented.

However, achieving the green ultra-low wear between steel and steel remains a challenge. In this work, a semi-solid deionized water (DIW)/sorbitan monostearate (Span 60) composite lubricant (DSP) is devised, achieving ultra-low wear at steel/steel interface. Compared with DIW lubrication, the friction coefficient of DSP was reduced by 75% and the wear rate was reduced to 2 orders of magnitude. At a contact pressure of 791.5 MPa, the wear rate also increases with the increasing number of cycles of 10,000 (5.82×10-8 mm3·N-1·m-1) and 20,000 (7.62×10-8 mm3·N-1·m-1), but ultra-low wear can still be achieved. The ultra-low wear was attributed to sufficient adsorption and the hydrogen-bond network of the lubricant at the friction pair surface, which effectively reduced the direct contact of the friction pair. This work inspirates the research of green ultra-low wear lubricants and promotes the broad application of ultra-low wear technology in engineering.","PeriodicalId":12442,"journal":{"name":"Friction","volume":"26 1","pages":""},"PeriodicalIF":6.8,"publicationDate":"2025-05-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143926944","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

When the contact is purely normal (i.e., no sliding), the term contact electrification is often used. It was proposed in 2019 by Laurence Marks and co-workers (Phys. Rev. Lett, 123, 116103) that flexoelectricity (i.e., strain gradient-induced polarisation) might be a key driver of triboelectricity at least in insulators. They explained how to determine flexoelectric surface potentials for Hertzian sphere-on-flat contacts and calculated appreciable values when the typical small size of surface asperities was considered. However, the theory developed so far is only valid when two contacting surfaces are in the loading stage where transferred charges are restricted within the contact area. However, nearly all experimental measurements of surface charge and potential are made at the end of the unloading stage when two surfaces are completely separated. Here, we develop a Hertzian (sphere-on-flat) flexoelectric non-adhesive contact electrification model that accounts for the Hertzian contact in both the loading and unloading stages. The impetus for the model is the fact that flexoelectric polarisation clearly decreases monotonically during unloading. For this reason, we find that the residual surface charges and potential (after a complete separation of two mating surfaces) are considerably altered if unloading is considered. Their magnitudes are much reduced, and their profiles take on a very different shape. The trends of increasing surface charge and potential magnitudes with increasing normal load are in agreement with experiments. The next major step will require the addition of adhesion to the loading-unloading model as this can be expected to further alter the evolution of strain gradients during the loading and unloading stages.","PeriodicalId":12442,"journal":{"name":"Friction","volume":"49 1","pages":""},"PeriodicalIF":6.8,"publicationDate":"2025-05-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143926950","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We find superlubric behavior for flat boundaries due to boundary slip, but finite friction for rough boundaries, due to bulk shear and the related energy dissipation in the bulk. The atomistic simulations reveal a preferred AA-type atomic stacking, which changes to TA-type stacking as the applied load is increased. This is accompanied by a loss of rolling motion of the particles in the highly condensed sheared packing.

Its excellent boundary lubricating capability comes from its unique bottlebrush structure. In this study, a biomimetic polymer containing 2-hydroxyethyl acrylate and 2-methacryloyloxyethyl phosphorylcholine (MPC) was synthesized. This polymer is structurally similar to lubricin and achieves a water-trapping capacity similar to that of lubricin through the design of the pMPC moiety. Atomic force microscopy (AFM) imaging indicates that changes in the molecular chain length and concentration lead to different self-assembled polymer structures. The lateral force between the AFM probe and silicon surface covered by the polymer demonstrates that the self-assembled structure of polymer molecules on the surface affects its boundary lubrication ability. When polymers are adsorbed onto the surface of articular cartilage to replace natural lubricin, the system exhibits extremely low friction (~0.028) under boundary film–liquid mixed lubrication conditions, which is close to the coefficient of friction (COF, ~0.024) of natural lubricin under the same conditions. The study of this biomimetic polymer provides a strategy for lubricating damaged cartilage during the initial stages of osteoarthritis development.","PeriodicalId":12442,"journal":{"name":"Friction","volume":"35 1","pages":""},"PeriodicalIF":6.8,"publicationDate":"2025-04-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143880792","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Our molecular dynamics simulations demonstrate that the first water layer adjacent to the surface plays an important role in interfacial friction. Applying a uniform strain to the surface (changing the lattice constant) can induce a significant change in friction and is quite different for the hydrophilic and hydrophobic cases. Specifically, in the hydrophilic case, there is maximum friction when the lattice constant approaches the preferential oxygen‒oxygen distance of the first water layer (a constant value), and the further it deviates, the smaller the friction. The maximum friction corresponds to the most ordered first water layer. While in the hydrophobic case, the friction increases monotonically with increasing lattice constant, which hardly changes the first water layer structure but only increases the difficulty of water molecular jump (meaning jump from one equilibrium position to another). Starting from the molecular jump in the first water layer, theoretical dependence of friction on the molecular activation barrier and shear velocity is established, which provides a reasonable explanation for the friction behavior. Moreover, the water transport behavior in nanochannels supports the finding of the friction dependence on the lattice constant, suggesting great potential for improving and controlling water transport. Our results not only provide a novel understanding of nanoconfined water friction but are also instructive for friction control and water transport.","PeriodicalId":12442,"journal":{"name":"Friction","volume":"140 1","pages":""},"PeriodicalIF":6.8,"publicationDate":"2025-04-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143872835","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the mechanism of blackening wear is still controversy. In this study, the impact of oxygen concentration on the blackening wear was investigated using a sealed double-contact friction tester by controlling the ventilation of argon gas. Then four types of oils, as well as steel balls and Si3N4 balls, were used to study the effect of oil decomposition on blackening wear. Finally, the effect of PPI decomposition was studied under dry friction condition for obtaining high friction temperature. The results indicate that iron oxides are the primary factor of blackening on the worn surface of PPI, while oil and PPI decomposition are the minor factor. At a concentration of 0.1% oxygen or when Si3N4 balls are used as rubbing-pair materials, there is only slight blackening wear on the PPI worn surface. Therefore, the influence of iron oxides on the blackening of PPI worn surfaces is crucial. Under low oxygen concentration (0.1%), higher unsaturation of oil may lead to slight blackening wear of PPI due to oil decomposition, but the impact is much lower. This study provides necessary insights into the mechanism of blackening wear of PPI cages.","PeriodicalId":12442,"journal":{"name":"Friction","volume":"68 1","pages":""},"PeriodicalIF":6.8,"publicationDate":"2025-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143866740","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Three batches of GO sheets with various lateral sizes were selected, and the lateral sizes were mainly within the ranges of 0.5±0.2, 5.9±2.1, and 59.1±17.1 μm. The weight concentration of the GO sheets in the aqueous lubricant ranged from 0.0005 to 0.8 wt%. The lubrication regime for the friction tests was kept at boundary lubrication. The GO sheets can enhance lubricity by entering the contact area and preventing the sliding surfaces from contacting each other directly, and lubricity is determined by the coverage of the contact area. For each batch of GO sheets, as the concentration increases, the coverage rate of the contact area increases; thus, the coefficient of friction (COF) and wear volume decrease. However, when the GO sheet concentration is very high, the COF approaches a stable value since the contact area is already fully covered by GO sheets, but the wear volume increases slightly due to the high acidity. Moreover, GO sheets with larger lateral sizes can lead to a smoother contact interface. Therefore, at the same concentration, GO sheets with larger lateral sizes can lead to lower COFs and wear volumes. These findings provide a general strategy for improving the performance of lubricants with two-dimensional (2D) material additives in a broad range of mechanical applications.","PeriodicalId":12442,"journal":{"name":"Friction","volume":"53 1","pages":""},"PeriodicalIF":6.8,"publicationDate":"2025-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143872927","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The results were then combined with first-principles calculations to investigate the chemical state of the boundary layer in a state close to that of sliding. As a result, the iron salt of a phosphate ester and the coordination structure of an iron-centered phosphate ester were generated by OLAP-added oil and aggregated near the interface with the base material during friction. Furthermore, a boundary friction model that considers non-Newtonian characteristics was applied to an experimentally obtained friction diagram to verify the effect of the boundary layer on the friction characteristics. The maximum effective viscosity calculated from a function obtained by fitting the friction diagram was approximately 3,000 Pa·s, which was equivalent to that of common grease. These results indicated that the characteristic frictional properties of the OLAP are due to the action of its grease-like organic boundary layer.","PeriodicalId":12442,"journal":{"name":"Friction","volume":"31 1","pages":""},"PeriodicalIF":6.8,"publicationDate":"2025-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143866396","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the search for a superlubricious oil system applicable to industrial fields remains a major challenge. In this work, we demonstrate for the first time that precisely employing polyether modification for silicone oil molecules could induce direct superlubricity and superlow wear for engineering steel tribopairs. Superlubricity originates from the fact that polyether-modified silicone oil (PESO) can effectively employ polyether functional groups to interact with friction surfaces, during which a complex tribochemical reaction process can be induced under the catalytic role of friction, where an organic lubricious film composed mainly of carbon, silicon and oxygen can be induced in situ, which can not only effectively passivate friction surfaces but also enable superlubric sliding by virtue of its easy-to-shear nature. Furthermore, iron oxides and chromium oxides could also be confirmed to be distributed within the tribofilm, which is desirable for increasing the load-bearing capability of the tribofilm and toughness. Thus, a remarkable superlubricity of 0.01 without running-in combined with superlow wear was realized at the same time. The results of this work show high promise in promoting the industrial use of oil superlubricity and revolutionizing the development of mechanical systems.","PeriodicalId":12442,"journal":{"name":"Friction","volume":"33 1","pages":""},"PeriodicalIF":6.8,"publicationDate":"2025-04-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143858024","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
