This poses significant challenges in aerospace, particularly when operating in harsh environments. Despite decades of data gathering and empirical model development, accurately predicting SPE remains challenging due to the complexity of the phenomenon and the variability in testing conditions. In this study, we compiled a database of over 1000 erosion tests on metals from existing studies and internal experiments, noting material properties, test conditions, and literature metadata. Machine learning (ML) models, including Random Forest, Neural Networks, Support Vector Regression, and XGBoost were employed to predict erosion rates. XGBoost was most performant, achieving a mean absolute error of 15–16 % on test data. Model performance was further validated by predicting results published in the ASTM G76 standard; predictions were within the interlaboratory standard deviation for tests at 70 m/s. Feature importance and partial dependence plots were used to evaluate the influence of different variables on erosion predictions. While particle velocity, particle size, and impact angle show the expected influence, features such as target density and Poisson’s ratio showed exaggerated effects due to their role in classifying outlier materials. These results show the promise of ML for SPE prediction across a range of conditions and suggest that the broader erosion literature is valuable for quantitative predictions, while also acknowledging limitations in the ML approach, particularly where data sparsity and feature correlations hinder the accurate assessment of feature influence.</div></div>","PeriodicalId":23238,"journal":{"name":"Tribology International","volume":"211 ","pages":"Article 110903"},"PeriodicalIF":6.1,"publicationDate":"2025-06-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144306981","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}

These issues are exacerbated under minimum quantity water lubrication (MQWL), where maintaining material removal efficiency and surface quality becomes even more difficult. In this study, molecular dynamics simulations were employed to investigate the CMP process of β-SiC under ultrathin water film lubrication, focusing on the impact of different groove depths and groove widths on material removal rate (MRR), surface roughness, temperature distribution, and residual stress. The results reveal that although increasing groove depth and width reduces MRR, it significantly helps to suppress residual stress and polishing-induced temperature rise, which enhances surface integrity. Quantitatively, the presence of an ultrathin water layer reduced maximum temperature by up to ∼30 % and residual von Mises stress by ∼20 % compared to dry polishing, while achieving smoother surfaces (Root Mean Square global - RMSg improved by ∼10–15 %) especially at groove depths of 8–16 Å and widths of 0–4 Å. Additionally, the water molecules dissociate under mechanical stress into –OH, –H, and –O– groups, with –OH forming strong chemisorption bridges between the SiC substrate and abrasive particles. This interaction promotes chemical bond breaking and contributes to a higher MRR than that observed in non-lubricated environments. These findings not only demonstrate the effectiveness of MQWL in reducing thermal and mechanical damage during CMP but also provide a novel atomic-scale understanding of the chemomechanical synergistic mechanisms under ultrathin water lubrication. The insights gained here may guide the optimization of surface patterning and lubrication strategies for advanced semiconductor CMP applications.</div></div>","PeriodicalId":23238,"journal":{"name":"Tribology International","volume":"211 ","pages":"Article 110899"},"PeriodicalIF":6.1,"publicationDate":"2025-06-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144279317","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 decomposition temperature of the modifier is typically considered the maximum operating temperature of the nano-additive. However, we observed that the sedimentation temperature of copper nanoparticles modified by dialkyl dithiophosphates (DDP) (referred to as CuDDP) in base oil is significantly lower than the decomposition temperature of the modifier itself, and the sedimentation rate varies with the polarity of the base oil. The thermal failure mechanism of CuDDP was analyzed. The results demonstrate that competitive adsorption of the outermost modifier by polar groups of the base oil and the sub-surface modifiers of nanoparticles is the primary cause of thermal instability, which occurs prior to structural changes in the modifier itself. The polar groups of base oil generate stronger electrostatic interactions with the polar end of the modifier, thereby promoting modifier desorption. Consequently, particle sedimentation is attributed to modifier desorption, which disrupts dispersion stability. This study provides critical guidance for designing sustainable nano-additives with high-temperature resistance and offers broad applicability for the practical applications of organic-inorganic hybrid nanoparticles.</div></div>","PeriodicalId":23238,"journal":{"name":"Tribology International","volume":"211 ","pages":"Article 110888"},"PeriodicalIF":6.1,"publicationDate":"2025-06-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144291488","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}
