Although literature data are abundant, they are often non-standardized and are reported under highly variable conditions, which hinders their systematic reuse for predictive modeling. This study introduces a machine learning (ML) framework that exploits heterogeneous data with a focus on physical relevance and robustness. A dataset of approximately 4100 points (including 410 friction coefficient points) was compiled from an extensive literature review. Two modeling scenarios are defined: the first uses mechanical, structural, and tribological descriptors; the second adds chemical composition features, offering more detail but reducing dataset size. Six machine learning models are evaluated under standardized training conditions to predict friction. Model performance is evaluated using standard metrics. Extra Trees (ET) and Artificial Neural Networks (ANNs) achieve the highest performance. SHAP (SHapley Additive exPlanations) analysis identifies temperature and hertz pressure as dominant predictors, consistent with the tribological observations. Incorporating chemical composition improved prediction accuracy but reduced dataset size, highlighting a key trade-off between data completeness and feature richness. SHAP analysis shows that while temperature and hertz pressure remain key predictors, the importance of humidity increases, reflecting that chemical inputs enhance not only accuracy but also the physical interpretability of the models. The results demonstrate that literature-based data can support robust and physically meaningful friction modeling when feature richness is balanced with careful control of data quality.</p></div>","PeriodicalId":806,"journal":{"name":"Tribology Letters","volume":"73 4","pages":""},"PeriodicalIF":3.3,"publicationDate":"2025-08-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s11249-025-02056-2.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144897167","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the microscopic contact mechanism remains poorly understood due to the complexity and randomness of scraping. To overcome the limitations of traditional single-Gaussian rough surface models in mixed lubrication analysis, this study develops a novel bi-Gaussian stratified contact stiffness model. This model achieves a more accurate description of interface contact behavior by accurately characterizing the topography features of the scraped surface. Based on the probability density function (PDF) of bi-Gaussian surfaces, the modified Brake model is used to develop a solid contact stiffness model for the scraped surface. This model is then corrected by treating the lower Gaussian surface as a substrate. Subsequently, the average Reynolds equation is applied to model the liquid contact stiffness and solid–liquid coupling through the oil film thickness. Contact stiffness experiments conducted on scraped surfaces with three accuracy levels verify the proposed model. Finally, parametric studies are performed using the established model to evaluate the effects of both the proportion and roughness of the upper Gaussian surface on the resultant solid and liquid contact stiffness. The results indicate that under a 40 kN load, increasing the proportion of the upper Gaussian surface from 40 to 90% increased the total contact stiffness by approximately 21%, and reducing its roughness from 6 μm to 1 μm increased the total contact stiffness by approximately 52%.</p></div>","PeriodicalId":806,"journal":{"name":"Tribology Letters","volume":"73 4","pages":""},"PeriodicalIF":3.3,"publicationDate":"2025-08-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144897160","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As for the extreme conditions, the performance of traditional liquid lubricants would be degraded, which causes significant harm to the safe and reliable operation of equipment. Therefore, the development of a high-efficiency composite lubricant is particularly important. In this study, MXene@Triethanolamine borate nanocomposite were prepared via the ultrasonic intercalation method. Furthermore, the composites were characterized by scanning electron microscopy, X-ray diffraction, and Fourier transform infrared spectroscopy. The tribological properties of intercalated MXene@TB in the BMIMPF6 ionic liquid were evaluated under current using a ball-on-disk tribometer. The average friction coefficient of lubricant with 0.3% intercalated MXene@TB-1 was reduced by 9.8%, and its wear volume was also decreased by 36.1%. Additionally, the application of current can enhance the tribological performance of lubricant. Specifically, the wear volume of <i>int-</i>MXene@TB-2 was decreased by 52% due to the current-induced ion migration and lubricating film repair. Moreover, the application of current promotes the movement of nanoparticles within the ionic liquid, minimizing aggregation and further enhancing the formation of the lubrication film. The lubricant nanocomposite with high-efficiency friction reduction and anti-wear properties can be further applied in current-carrying friction field.</p><h3>Graphical abstract</h3>\u0000<div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":806,"journal":{"name":"Tribology Letters","volume":"73 4","pages":""},"PeriodicalIF":3.3,"publicationDate":"2025-08-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144810930","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
