The differences in microhardness and microstructure across different zones of these joints contribute to the occurrence of uneven wear. This study proposes a laminar plasma inhomogeneous quenching (LPIQ) method to address this issue and comprehensively investigates the effects of LPIQ on wear and rolling contact fatigue (RCF) behaviors of two types of rail welded joints. The results indicated that LPIQ treatment induced grain refinement (1.63–2.04 μm) in different zones of two types of welded joints. Simultaneously, this treatment facilitated the recrystallization process dominated by continuous dynamic recrystallization and geometric dynamic recrystallization. The proportion of recrystallized grains in the quenching zone exceeded 55 %, with the difference between various zones being less than 1 %. The high uniformity of the microstructure following LPIQ treatment contributes to balancing the wear across different zones of the welded joints, yielding wear homogenization index of 20.75 % for quenching thermite welded joint (QTW) specimens and 4.96 % for quenching flash welded joint (QFW) specimens. Furthermore, the RCF damage observed in QFW specimens is more complex and severe compared to that in QTW specimens. The quenching zones of the specimens following the LPIQ treatment are rich in high-angle grain boundaries, whereas the substrate predominantly consists of low-angle grain boundaries. This differentiated distribution of grain boundaries enhances the joint's resistance to damage and inhibits crack propagation towards the substrate. Additionally, the kernel average misorientation (KAM) value in the quenching zone significantly increases compared to that of the substrate, and its distribution exhibits a high degree of uniformity.</div></div>","PeriodicalId":23970,"journal":{"name":"Wear","volume":"580 ","pages":"Article 206236"},"PeriodicalIF":5.3,"publicationDate":"2025-07-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144604254","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}

After incorporating the thermophysical database of 18Cr2Ni4W in DEFORM finite element software, it was used to simulate carburizing at temperatures of 930 °C, 950 °C, 970 °C, respectively, and the subsequent heat treatment processes to obtain hardened layers with a 4.5 mm depth. The distributions of carbon concentrations, martensite, and retained austenite fractions after carburizing heat treatment were simulated and validated against experimental data. The results reveal that the surface carbon concentration and hardness increased with the rise of carburizing temperature. The measured hardness distributions in experiments are consistent with the DEFORM simulations, indicating the validity and accuracy of the finite element model. Tensile tests of the carburized surface indicates that the tensile strengths of the samples obtained from different carburizing temperatures all exceed 2000 MPa. Ductility decreases significantly with the increasing carburizing temperature. The sliding wear tests show that the sample carburized at 970 °C has the smallest wear rate (1.33 × 10⁻⁸ mm³ N⁻¹ mm⁻¹) as compared to the 930 °C and 950 °C cases, in which Si₃N₄ counterbodies were applied. The wear resistance of the sample carburized at 950 °C is merely better than that carburized at 930 °C. The primary wear mechanisms are found to be adhesive oxidation wear accompanied by abrasive wear. The morphology and element distribution tests of the Si₃N₄ counterface pin after the friction and wear experiments indicate the materials transfer from the carburized 18Cr2Ni4W alloy surface to the counterbody. The most obvious aggregation of element oxygen was found on the counterface that contacts the 930 °C carburized sample, implying the most severe adhesive oxidation wear. Finite element simulation of temperature fields during friction and wear show that the maximum temperature at the contact point of the sample carburized at 970 °C was 50 °C lower than that of the sample carburized at 930 °C, so that the oxidation wear of the sample carburized at 970 °C was significantly alleviated, which accord with the experimental results. Therefore, the increase of the volume fraction of carbides, along with the reduction of temperature during friction, enhanced the wear resistance of the carburized layer.

However, the high hardness and densely uneven distribution of SiC particles lead to frequent impacts and unstable loading on abrasive grains during conventional grinding (CG), accelerating grain wear and degrading workpiece surface quality. This paper proposes an ultrasonic vibration-assisted grinding (UVAG) method using single diamond grain (SDG) to investigate grain wear behavior and its influence on the material removal. The grinding performance of the SDG, the evolution of grinding forces and grain morphology during wear, and their effects on material removal are analyzed. Results show that UVAG introduces dynamic oscillatory loads, which effectively reduce peak forces, mitigate grain wear, and extend the steady wear stage. Compared with CG, UVAG lowers the grinding force by 19.7 % in the initial state and by 17.3 % during steady wear. The diamond grain primarily undergoes abrasive wear and tends to adhere to the Al matrix and brazing alloy. Under UVAG, the wear width and height of the cutting edges are reduced by 24.9 % and 21.4 %, respectively.
