Results show that the tool life of the cermet tools improved by up to 5.6 times compared to the carbide tools. Additionally, as the cutting speed (<em>v</em>) increases, the tool life of the cermet tools increases by 83 %, whereas that of the carbide tools decreases by 58.3 %. The primary wear mode of the cermet tools was oxidative wear for <em>v</em> = 100 and 160 m/min, whereas that of the carbide tools was coating peeling. However, at <em>v</em> = 220 m/min, both tools exhibited coating peeling and notch wear. Moreover, surface roughness, surface microhardness, and residual compressive stress increased with the progression of tool wear. These findings reveal that cermet tools are more suitable for high-speed turning and are superior to carbide tools in tool life and machined surface integrity, thereby ensuring high-quality machining and improved machining efficiency.</div></div>","PeriodicalId":23970,"journal":{"name":"Wear","volume":"576 ","pages":"Article 206121"},"PeriodicalIF":5.3,"publicationDate":"2025-05-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144068030","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}

In this study, a novel HEA, Al<sub>0</sub>.<sub>25</sub>FeCoNiVTi<sub>0</sub>.<sub>1</sub>, was designed with multiscale precipitated phases. The alloy's microstructure and dislocation density were further tailored via hot rolling followed by annealing treatments. Although the as-rolled condition exhibited the highest strength and hardness, its excessive dislocation density caused localized stress concentrations and microcrack formation, undermining the integrity of the oxide film and resulting in the poorest wear resistance. In contrast, the sample subjected to hot rolling and subsequent moderate annealing for 2 h (HR-2h) demonstrated significantly enhanced wear performance, achieving a 15.6 % reduction in the coefficient of friction and a 28.7 % decrease in wear rate relative to the homogenized state, despite exhibiting slightly lower strength and hardness. This enhancement is attributed to the synergistic effects of multiscale precipitates, which improved resistance to shear deformation and facilitated the formation of a dense, stable oxide film that effectively mitigated wear damage. Notably, the HR-2h sample also exhibited excellent high-temperature wear resistance, with the wear rate at 873 K reduced by approximately 83.7 % compared to that at room temperature. These findings challenge the traditional assumption that higher hardness correlates with better wear resistance and highlight the critical role of microstructural heterogeneity and dislocation density modulation in optimizing tribological performance.

Optimal lubrication was achieved with a groove spacing of 1.6 mm, yielding a friction coefficient of 0.198—a reduction of 76 % compared to untextured surfaces (0.827). This substantial decrease is attributed to an “extrusion spreading” mechanism, where EP/FGi in the grooves forms a protective lubricating film at the contact interface, reducing direct metal contact and enhancing self-lubrication. Finite element analysis further revealed that groove spacing influences GCr15's plastic deformation under stress, driving EP/FGi to extrude from grooves and form a stable transfer film, enabling sustained lubrication through a self-compensating effect. These findings provide theoretical guidance for optimizing groove texture geometry and assessing wear characteristics, underscoring a promising approach to enhancing wear resistance in high-performance bearing applications.</div></div>","PeriodicalId":23970,"journal":{"name":"Wear","volume":"576 ","pages":"Article 206119"},"PeriodicalIF":5.3,"publicationDate":"2025-05-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143942799","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 challenges are exacerbated by additively manufactured Inconel 625, as its anisotropic properties make machining more difficult. This study focuses on drilling Inconel 625, a widely used nickel-based superalloy, owing to its critical role in various industrial applications. Drilling operations are essential in areas such as aerospace manufacturing, where precision, hole quality, and efficiency are of utmost importance. The study aims to enhance the machinability of wire-arc additively manufactured (WAAMed) Inconel 625 by employing sustainable nanofluids strategies. Hexagonal boron nitride (hBN), graphene-based mono nanofluids, and hybrid nanofluids were synthesised. Further, the nanofluids were thoroughly characterized for their volumetric specific heat capacity, wettability, and dynamic viscosity. A hybrid nanofluid with (hBN to graphene) exhibited excellent lubricating and cooling performance. The machinability of both WAAM IN625 and wrought IN625 was evaluated under dry conditions, hBN and graphene mono nanofluids, and hybrid nanofluid-assisted drilling, focusing on metrics such as surface cutting temperature, surface roughness, hole circularity deviation, and tool wear and morphology. Results demonstrated that the hybrid nanofluid environment offered substantial advantages over dry machining, including a 37–41 % reduction in cutting surface temperature, a 41–45 % improvement in surface quality and a 53–54 % decrease in circularity deviation for both WAAM and wrought IN625. Furthermore, tool wear was minimised, with less adhesion and abrasive wear, resulting in a much longer tool life.</div></div>","PeriodicalId":23970,"journal":{"name":"Wear","volume":"574 ","pages":"Article 206090"},"PeriodicalIF":5.3,"publicationDate":"2025-04-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143894661","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}

To this end, this study firstly proposes a new node-improved form of energy dissipation wear model, which is more sensitive to the contact behavior of the asperity body in the overfilled region and the energy transfer process; it exhibits wear prediction results that are closer to the actual situation than the traditional model and improves the prediction accuracy of the corresponding relationship between the cycle time and the wear fatigue crack extension. Secondly, the acoustic emission deep learning detection and validation method of shaft wear fatigue under dynamic rotation is developed; 75,480 wear fatigue signal time-frequency map datasets are established with shaft dynamic rotation experiments, and the convolutional self-encoder and multi-head attention mechanism recognition and detection network are trained. The recognition accuracy of the wear fatigue damage stage reaches 87.4 %.
