Opaque rough surface morphology is difficult to detect and observe in real time during the friction process. This poses a great challenge to accurately evaluate the interfacial properties of some types of engineering equipment, such as multi-turn superconducting coils, aero-engine bearings, and components. In this study, we first construct an evolutionary quantitative characterization relationship for the friction-morphology correlation. Then, we establish a frictional mechanics model and a morphological reconstruction method that achieves the reconstruction and prediction of rough surface morphology based on the evolution of friction force during the friction process. The above research methods make it possible to probe the interface during friction for opaque solids, and provide new ways to reveal the friction mechanism and predict friction behavior.

Fretting wear is a common material degradation phenomenon in contacting bodies due to contact loading constraints. It also commonly occurs in steel wires used for load-carrying cables. So, studying the fretting wear process of steel wires operating in a corrosive coal-extracting environment is important. In this study, a Finite Element (FE) model is developed for a better insight into fretting wear including the effect of corrosion. The energy wear model is combined with the Faraday's law of electrochemical corrosion to calculate the material damage due to fretting wear and the effect of corrosion produced from the oxide passive layer in a corrosive environment during the fretting process. The FE model simulates the fretting wear including the effect of corrosion on steel wires used in the corrosive environment of the coal mining hoisting system. The numerical simulation outcomes of fretting wear are compared with experimental results, with and without including the effect of corrosion. Both experimental and FE model results with corrosion reveal that corrosion significantly accelerates wear, leading to larger and deeper wear scars, especially under higher loads. The FE model predictions are closely aligned with the experimental data, validating its ability to predict wear depth, wear profiles, wear scars, wear volume, and changes in contact stress. The findings highlight the requirement of combining mechanical and the effects of electrochemical corrosion in fretting wear evaluations to prevent underestimating material degradation. This research highlights the importance of implementing the effective mitigation strategies, such as surface treatments and considering corrosion-resistant materials, to improve the durability of components in challenging engineering applications. Generally, the developed model provides valuable insights for optimizing material performance in environments where fretting wear and corrosion coexist.

Laser powder bed fusion (LPBF) 420 stainless steel reinforced with 5 wt% WC/W2C exhibit notable corrosion and wear resistance. However, the stability of the reinforced particles and stainless steel shows an inverse relationship with fluctuating pH levels. This research investigates the corrosion resistance and tribo-corrosion performance of WC/W2C particles strengthened LPBF 420 stainless steel composites in acidic, neutral, and alkaline environments. The open circuit potential (OCP) in acidic environment is −0.48 VSCE, which is 0.34 VSCE and 0.05 VSCE lower than that observed in neutral and alkaline solutions, respectively. The maximum depth recorded after tribo-corrosion testing follows the trend of acidic (5 μm) > neutral (3 μm) > alkaline (0.6 μm), indicating the worst corrosion resistance and tribo-corrosion performance in acidic environments. The WC/W2C demonstrates dissolution in alkaline conditions, leading to diminished corrosion resistance compared to neutral solutions. However, the friction products formed in alkaline environments contribute to an enhanced coefficient of friction (COF) value and tribo-corrosion resistance when compared to neutral solutions.

This paper integrates Selective Laser Sintering (SLS) with Liquid Silicon Infiltration (LSI) to fabricate graphite/SiC composite materials. The graphite content is modified through multiple cycles of impregnation carbonization and graphitization. The results indicate that the microstructure of the composite materials significantly influences their tribological properties as the graphite content increases. When the graphite content is below 7.86 vol%, SiC forms a three-dimensional dual-continuous structure. The limited wear debris on the friction surface results in a relatively high average coefficient of friction (COF). Conversely, when the graphite content exceeds 79.83 vol%, a unique "sandwich" structure develops between the graphite and SiC. With this specific microstructural change, the average COF of the composites not only did not decrease but actually increased, while the mechanical properties gradually diminished and the thermal properties gradually improved. When the graphite content is within the range of 22.75 vol% to 34.59 vol%, the composite materials exhibit a lower average COF (0.26 ∼ 0.17) and wear rate (0.73 ∼ 6.69 × 10−6·mm3·N−1·m−1). By regulating the graphite content, the application range of the composite materials is broadened. This research lays the groundwork for future investigations into more complex factors affecting SiC ceramic composite materials.

A machine learning approach was developed to predict load-dependent power loss in gear pairs under mixed elastohydrodynamic lubrication (EHL). Using a homogenized mixed EHL solver, training data were generated, considering surface roughness and cavitation phenomena. A multimodal deep learning (MMDL) model improved regression performance for multimodal inputs. Validation against experimental data confirmed the model's reliability, achieving a maximum gear efficiency error of 0.07 %. The MMDL model with concatenation fusion was selected for its highest R-square value of 0.99166, significantly accelerating simulation speed by 0.05 %. This method can be applied to optimize gear design and provides an efficient solution to reduce power loss in automotive drivetrains, overcoming the limitations of conventional analytical and EHL methods.

This study presents Gallium liquid metal (LM) as the core material, with molybdenum disulfide (MoS₂) serving as the shell, to create nanoflower-like M@G microcapsules aimed at enhancing tribological performance. The M@G microcapsules were incorporated into the in-situ polymerization of carboxylated poly(urea-imide) for a PEEK/PTFE fabric liner (P-M liner) fabrication. under 24.96 MPa and rotational speed of 600 r/min, the wear rate and average coefficient of friction of the P-M liner decreased by 66.06 % and 22.82 %, respectively, compared to the pure sample. During the friction process, the liquid metal microcapsules infiltrated the counterpart, forming a dual-layer tribofilm with Ga-rich and C-rich films. This study demonstrates the superior tribological performance of liquid metal microcapsules, showing significant potential for high-speed friction applications.

Scratch tests on tungsten GLAD films examined friction anisotropy at various deposition angles (), normal forces (), and scratching directions (). A linear model of the coefficient of friction () revealed four behavior groups, ranging from isotropic ( = 0°and 30°) to orthotropic ( 60°). Intermediate angles (40° 60°) showed slight non-centrosymmetric anisotropy. Post-scratch analysis linked these behaviors to film morphology. A transition from dense to columnar structures, with columns elongated perpendicular to the atom flux, influenced plasticity. Less deformation occurred along scratching directions ( = 90°/270°) due to column chaining, resulting in higher friction. A mechanical model highlighted how morphology-driven plasticity variations explain the anisotropic behavior.

Three-phase coupled composites were manufactured to holistically evaluate their load-response mechanisms. Tribological properties in ball-on-disk tests were correlated with GF content and different applied loads. Tribological properties of embedded semirings were better than polymer semirings in semiring tests, resulting in the decrease of COF by 44 %, and the reduction in wear depth by 98.8 %. Embedded semiring with the inclusion of 3 wt% GF possessed remarkable tribological properties, as evidenced by COF of 0.071 and wear rate of 22.7 × 10−4 mm/h. Stress and strain distributions, as well as associated coupling mechanism among all three phases are revealed with the aid of FEA and MD simulation. Overall, this study offers a fundamental theoretical of polymer composites for self-lubricating bearings applications.

This study presents a comparative analysis of wear and frictional characteristics observed in two materials: a Zn-Al alloy and an in-situ reinforced Zn-Al/9 vol% ZrB2 composite in the dry as well as in the lubricated sliding state.Furthermore, to highlight the potential applications of the Zn-Al/9 vol% ZrB2 in-situ composite, a thorough comparative examination of its wear and frictional properties against commercially prevalent materials in tribological applications has been conducted. The results reveal promising outcomes, demonstrating comparatively lower wear and a higher frictional coefficient in dry sliding conditions. This unique combination of the developed material may be a promising candidate for use in possible braking and clutch materials systems. Conversely, in lubricated environments, the material exhibits low wear and a low COF, indicating its potential suitability for bearing and bushing applications. Moreover, this study not only enhances understanding of wear mechanisms but also opens the way for the innovative application of the Zn-Al/9 vol% ZrB2 in-situ composite in various industrial scenarios. These findings align well with the increasing demand for multifunctional materials in resource-conscious and dynamic industrial environments.

The study of how temperature affects the perception of the fluid food in the oral cavity is relatively scarce. In this paper, the lubrication properties, tastes, and their relevance of Baijiu were investigated at different temperatures by tribology, taste test, 1HNMR, rheology, and GC-MS component analysis. The variations in tastes are closely related to the contents of representative volatile compounds and the alterations in the structural system of ethanol-water. The impacts of temperatures on lubrication properties mainly come from the changes of intermolecular bonding force and viscosity. A link between Baijiu tastes and lubrication characteristics at different drinking temperatures was established. The optimum lubrication performance and tastes of Baijiu occur at the same temperature, which is 25°C. This research helps to evaluate the tastes and obtain the suitable serving temperatures for Baijiu.

The variations in tastes are closely related to the contents of representative volatile compounds and the alterations in the structural system of ethanol-water. The impacts of temperatures on lubrication properties mainly come from the changes of intermolecular bonding force and viscosity. A link between Baijiu tastes and lubrication characteristics at different drinking temperatures was established. The optimum lubrication performance and tastes of Baijiu occur at the same temperature, which is 25°C. This research helps to evaluate the tastes and obtain the suitable serving temperatures for Baijiu.</div></div>","PeriodicalId":23238,"journal":{"name":"Tribology International","volume":"206 ","pages":"Article 110593"},"PeriodicalIF":6.1,"publicationDate":"2025-02-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143387575","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}
