To effectively extend the service life of the disc cutter and improve tunnelling efficiency, it is necessary to optimize the disc cutter selection and tunnelling parameters. In this study, a discrete element method (DEM) model for cutting granite with a full-size disc cutter considering wear induced deformation has been established. The model accurately replicated the rock-breaking pattern of the disc cutter in granite and simulated the impact of surface deformation on the contact forces between the disc cutter and the rock during the cutting process. Comparative analysis revealed that in hard rock strata, circular-tip disc cutter outperforms flat-tip disc cutter in multiple aspects, including cutting force and wear. A new cutter wear evaluation index called cutter wear ratio (<em>CWR)</em> has been proposed, and the influence of disc cutter selection and tunnelling parameters on rock-breaking and wear control was explored by combining rock-breaking specific energy (<em>SE</em>). The <em>S</em>_{<em>core</em>} index, which comprehensively considers rock-breaking efficiency and wear control, is introduced to represent the combined performance for various tunnelling parameter combinations. The optimal parameter combinations for different shield tunnelling demands are analysed. In the future, engineers in similar projects can optimize tunnelling parameters by balancing the different requirements for rock-breaking efficiency and wear control, based on the research findings of this study.</div></div>","PeriodicalId":23970,"journal":{"name":"Wear","volume":"578 ","pages":"Article 206182"},"PeriodicalIF":5.3,"publicationDate":"2025-06-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144221528","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}

Adhesion, plastic deformation, and tribo-oxidation appear on the worn surface of the Ni–W coating. Delamination, which is related to the tribo-layer type, is found to dominate the material removal process of the Ni–W coatings. Plastic deformation and oxidation prompt the formation of a mechanical mixed layer (MML) and an oxide layer (OL) on worn surface of the Ni–W coating as it slides against the metal counterparts. AISI 52100, which has a high hardness and deformation resistance, can lead to the formation of a large-area MML around the OL and reduce the tribo-layer delamination. Tribo-oxidation controls the formation and detachment of the protective OL during the wear process of the Ni–W coating as it slides against the ceramic counterparts. Decreasing the tribo-chemical reaction activity of the coutact surfaces between the Ni–W coating and the counterparts could diminish OL delamination. Owing to their high deformation resistance and thermal conductivity, WC–Co composite can highly improve the tribological performance of the Ni–W coating by inhibiting delamination.

Particle measurements were conducted using a tread brake dynamometer on three types of brake blocks commonly employed in railway vehicles, all under identical conditions. The results were compared to identify their emission characteristics. Among the tested brake blocks, the sintered composite brake block emitted the smallest PM2.5 particle mass—fine particulate matter with a diameter of 2.5 μm or smaller. The brake blocks emitting the highest PM2.5 emissions varied with the applied pressing force: under low pressing force, the organic composite brake block emitted the most particles, while under high pressing force, the cast iron brake block emitted the most. In addition, a linear relationship was observed between the wear on the brake block and the PM2.5 particle mass, with variations depending on the material. The PM2.5 particle emission rates per wear unit were determined to be 1.7 %, 0.99 %, and 0.11 % for the organic composite, sintered composite, and cast iron brake blocks, respectively, with the organic composite brake block showing the highest emission rates.

Surface engineering methods have shown promise in enhancing the surface performance of titanium, improving wear and corrosion resistance. This study investigates the tribological and microstructural characteristics of laser-microtextured Ti-6Al-4V ELI (Extra Low Interstitial) alloy discs evaluated against ultrahigh molecular weight polyethylene (UHMWPE) and polyether ether ketone (PEEK) pins, with a focus on potential biomedical applications. Four distinct surface texturing patterns were created by varying the texturing area fraction from 5 to 20 %. A control group of Ti-6Al-4V ELI alloy discs without any texture was used for comparison. The microstructure and mechanical properties of the microtextured Ti-6Al-4V ELI alloy discs were thoroughly investigated using scanning electron microscopy, energy dispersive spectroscopy, X-ray diffraction, and nanoindentation. The tribological characteristics of the laser surface modified Ti-6Al-4V ELI alloy discs articulated against UHMWPE and PEEK pins were determined using a pin-on-disc tribometer under lubricated sliding conditions, with fetal bovine serum serving as the lubricant. The analysis of the microstructure of the laser microtextured Ti-6Al-4V ELI alloy showed that the grain structure α-Ti phase and β-Ti phase was refined, and titanium oxides were present, which led to an increase in nanohardness. Additionally, the texturing patterns on the Ti-6Al-4V ELI alloy discs reduced the coefficient of friction due to the hydrodynamic lubrication effect, compared to untextured discs. Moreover, it was observed that wear on UHMWPE and PEEK was reduced when they interacted with textured Ti-6Al-4V ELI discs. Laser surface texturing of Ti-6Al-4V ELI alloy surfaces offers a promising approach to enhance the tribological performance of biomedical implants. The improved interaction between the Ti-6Al-4V ELI alloy and polymer materials like UHMWPE and PEEK could lead to longer-lasting implant components with lower failure rates.</div></div>","PeriodicalId":23970,"journal":{"name":"Wear","volume":"570 ","pages":"Article 205931"},"PeriodicalIF":5.3,"publicationDate":"2025-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144230473","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}

A numerical analysis of the forging process, has enabled to estimate the main contact parameters such as contact pressures, sliding velocities and interface temperatures. The concerned forging process involves 38MnSiV5 billets with X38CrMoV5 tools. The range of studied contact pressures is between 100 MPa and 350 MPa; the range of sliding velocities is between 10 mm/s and 125 mm/s. For each type of zone, two configurations were identified: one with maximum contact pressure and another with maximum sliding velocity, both occurring at 1290 °C. To understand and analyse the thermal and mechanical evolutions at the part-tool interface during forming cycles, a multiscale approach is proposed studying new, mid-life and end-of-life crankshaft hot-forging tools. First, at a microscopic scale, the evolution of the mechanical properties of the oxidized layers on the tool are identified by nanoindentation according to the three levels of life. Secondly, at a mesoscopic scale, the identified industrial contact conditions are experimentally reproduced, on the WHUST (Warm and Hot Upsetting Sliding Test) tribometer, developed at the LAMIH. The used contactors come from industrial tools and feature non-conventional real and worn geometries. The WHUST results are then involved to determine friction indicators over the tool life cycle for the various geometric zones. Oxide layers, especially iron oxides (FeO, Fe₂O₃, Fe₃O₄), grow strongly during forming cycles, but differently depending on the geometry of the zones.

Engineering ceramics are potential substitutes for cermets, especially in corrosive and high-temperature environments. Polycrystalline diamond (PCD), an extra-hard cermet, is also a good candidate for these applications. Wear rates and mechanisms of alumina (96 % Al₂O₃), zirconia-toughened-alumina (ZTA 11 % vol. zirconia), zirconia (ZrO₂), boron carbide (B₄C), and PCD were compared to WC/Co (7 % wt. cobalt) in a high-stress abrasion test based on ASTM B611-21, using alumina and sand as abrasives. Sand was approximately 10 times less severe than alumina in tests with WC/Co and ZTA, likely due to its lower hardness and smaller initial size. When considering all tested materials, tests using sand as the abrasive revealed PCD with the lowest wear rate, 10 times lower than WC/Co, while Al₂O₃ presented the highest wear rate, 350 times greater than WC/Co. The comminution caused by the materials in both abrasives was evaluated.
