By incorporating crystallographic effects on dislocation mobility and capturing subsurface dislocation transport and trace line formation, the model reveals intricate microstructural features that influence plastic deformation, surface topography, and contact area evolution. Unlike continuum-scale simulations, which lack the resolution to capture microstructural details, or discrete simulations, which fail to couple microstructure-driven plasticity with tribological contact, this model bridges these gaps.

The results show that samples with groove spacing and width in the hundreds-micron inhibit cavitation damage. Among the samples with four different ratios of groove width to groove spacing (0.8, 0.82, 0.96, 1.75), the cavitation resistance of the material increases with the increase of the ratio. The larger the dimensionless erosion performance parameters, the weaker the anti-cavitation performance. An optimal array groove structure can significantly reduce cavitation damage compared to the polished sample. Especially, the sample with groove width <em>L</em>= 700 μm and groove spacing <em>W</em>= 400 μm exhibits the longest nominal incubation period (25.05 hours) and the minimal cumulative mass loss (10.92 mg) after 50 hours of cavitation, demonstrating the best cavitation resistance.

This study investigates the cooling/lubrication effect using an inverse thermo-mechanical model to support the understanding and optimization of sustainable cooling strategies. A hybrid analytical–experimental method is developed for determining the heat partition ratio and the convective heat transfer coefficient (h), which are critical to understanding thermal behavior in grinding. The inverse modeling approach considers the thermal behaviour of coolants and workpiece materials under elevated temperatures, where their thermo-physical properties differ significantly from those at room temperature. It further incorporates the effects of grinding parameters, wheel-workpiece contact length, and coolant supply conditions. Additionally, chemical reactions in the grinding zone, which can either absorb or release heat, are accounted for, further influencing heat transfer dynamics. The model is applied to evaluate several eco-friendly cooling/lubrication techniques, including cryogenic liquid nitrogen, carbon dioxide, minimum quantity lubrication (MQL), and their hybrid combinations, and compared to conventional flood and dry grinding. Key performance indicators such as grinding forces, temperature, surface finish, and elemental composition are analyzed. A generalized formula for the heat partition ratio is proposed based on the inverse method, enabling consistent evaluation of thermal effects across different cooling conditions. This integrated modeling approach enhances the understanding of coolant behavior in realistic grinding environments and supports the transition toward sustainable, high-efficiency manufacturing by guiding the selection and optimization of environmentally friendly cooling/lubrication methods.</div></div>","PeriodicalId":23238,"journal":{"name":"Tribology International","volume":"209 ","pages":"Article 110746"},"PeriodicalIF":6.1,"publicationDate":"2025-04-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143881626","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}

Results showed that the cage plays a crucial role in enhancing ball-raceway lubrication by redistributing lubricant across ball surfaces, with its effectiveness governed by positional clearances, grease type, and cage design.

When the electric field across a non-conducting lubricant film exceeds its dielectric strength, electrical discharges occur, causing surface damage to machine elements. Surface asperities amplify the local electric field, leading to microscale discharges and micro-pitting in the areas corresponding to the minimum film thickness within the elastohydrodynamic lubrication (EHL) regime. This study investigates the effect of asperities on local electric fields and introduces a field enhancement parameter to quantify the influence of various asperity geometries, including hemispheres, semicylinders, hyperboloid tips, hyperbolic blades, and two-dimensional sinusoidal wavy surfaces. The analysis results indicate that for a given film thickness, the enhancement effect is strongly dependent on the radius of curvature of the asperity tip, and that as the radius increases, the enhancement effect reduces and diminishes. The proposed method helps effectively predict the electrical-breakdown voltage for known asperity characteristics, offering valuable insights into the nature of EIBD, useful for the design of reliable lubricated systems working under high electric fields.</div></div>","PeriodicalId":23238,"journal":{"name":"Tribology International","volume":"209 ","pages":"Article 110742"},"PeriodicalIF":6.1,"publicationDate":"2025-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143887329","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}
