Scratch tests were conducted at normal loads of 5 N and 10 N, and surface profiles were analyzed using profilometry, while scanning electron microscopy (SEM) and electron backscatter diffraction (EBSD) provided insights into microstructural changes and deformation mechanisms at the subsurface. Results indicated that low-porosity samples exhibited less material removal and a shallower tribologically transformed layer, with higher plastic deformation, dislocation density, and stronger pile-up formation at the edges of the scratch. In contrast, high-porosity samples displayed more extensive material removal, thicker transformed layers, and heterogeneous deformation, with pores acting as stress concentrators that facilitated crack initiation and propagation. The friction coefficient increased with load, particularly for low-porosity samples, due to a higher accumulation of material resisting the indenter’s movement. These findings highlight the significant role of porosity in governing the tribological performance and mechanical behavior of sintered steels, providing valuable insights for both mechanical and biomedical engineering applications.</div></div>","PeriodicalId":23238,"journal":{"name":"Tribology International","volume":"209 ","pages":"Article 110674"},"PeriodicalIF":6.1,"publicationDate":"2025-03-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143747985","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 resulting DES lubricants exhibit favourable physicochemical properties and excellent lubrication performance. Notably, the L-Proline /Oxalic acid DES demonstrates superior lubrication performance, resulting in a substantial decrease in both friction (∼46–78 %) and wear volume (∼61–91 %) compared to PEG 200 and choline chloride/urea across all tested temperatures. Furthermore, in-depth analysis of the worn surfaces reveals the formation of a tribo-chemical film derived from L-Proline based DESs, consisting of hydrocarbon (CxHy), oxy metal nitride (Ti-N-O) fragments, along with titanium oxide/hydroxide-rich layer.

However, as a complex process, the accurate prediction of tool wear remains a challenging project. In this paper, the 2D modeling and simulation of tool wear during cutting Inconel718 are studied by using the coupled Euler-Lagrange (CEL) finite element method. Based on the temperature effect, a mathematical model of the wear rate of cemented carbide tools was established with comprehensive consideration of the abrasive, adhesive, and diffusive wear mechanisms. The corresponding mathematical model of abrasive wear rate was established during cutting by combining with the thermal hardness data and focusing on the influence of the abrasive wear in the abrasive grain movement mode on the wear rate. In the prediction of flank wear, the volume loss of the tool flank surface is related to the wear rate, and the corresponding mathematical model of flank wear is established based on temperature effect. Finally, the secondary development of ABAQUS is carried out using Python language, and tool wear subroutine is written to extract relevant parameters from the ABAQUS output database to calculate the tool wear rate. Through studying the evolution of the geometric shape of the rake and flank tool face wear and the change of the rake and tool flank face wear, and the orthogonal turning test which is carried out to observe and analyze the tool wear, the accuracy of the established tool wear model was verified to achieve the prediction of the tool wear. Compared with the test results, the prediction error of tool wear is less than 15 %. The equation of tool wear rate and cutting model proposed in this paper are helpful to improve the prediction accuracy of tool wear in cutting process.</div></div>","PeriodicalId":23238,"journal":{"name":"Tribology International","volume":"208 ","pages":"Article 110662"},"PeriodicalIF":6.1,"publicationDate":"2025-03-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143738136","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}

Thermal effects can accelerate wear, induce plastic deformation, and contribute to thermal fatigue. Reliable modelling of wheel-rail contact that considers friction-induced thermal effects is desirable for the accurate prediction of wheel-rail interface deterioration. Several analytical and numerical models have been proposed to simulate thermal or thermomechanical wheel-rail loads but have rarely been validated, especially in high slip ratio scenarios where flash temperatures exceed 200 °C. This study develops and experimentally validates a three-dimensional thermomechanical finite element (FE) wheel-rail contact model for high slip ratio conditions, with contact temperatures reaching 360 °C. The model incorporates key mechanical parameters, including wheel loads, coefficients of friction, and slip ratios. Simulated rail surface temperatures across various slip ratios (5 %, 10 %, and 15 %) are compared with the flash temperatures measured with an onboard infrared thermal camera, showing good agreement with a maximum deviation of 9.9 %. This confirms the reliability of the model for simulating wheel-rail contact under thermal effects.</div></div>","PeriodicalId":23238,"journal":{"name":"Tribology International","volume":"209 ","pages":"Article 110666"},"PeriodicalIF":6.1,"publicationDate":"2025-03-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143739125","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The slipping dynamic model of FCBs is established. We examine how the slippage and nonlinear vibration properties of FCBs are affected by thermal deformation, rotating speed, and waviness. The findings indicate that the rise in rotational speed, waviness amplitude and wave number all cause the increased ball-raceway contact stiffness coefficient. The rise in the amplitude of waviness as well as wave number can have the effect of inhibiting slippage. However, they can be too large resulting in an abnormal inner ring vibration. The increase in rotational speed can exacerbate slippage. Meanwhile the thermal deformation also has the effect of inhibiting slippage. The maximum fundamental frequency error between simulation and experiment is 0.37 %.
