The grease analysis and electrical discharge tests were conducted using a ball-on-disc rig to characterize the lubrication and electrical properties of conductive greases with ionic liquid, while recording the evolution of electrical discharge processes in EHD contacts lubricated with conductive grease. Firstly, the grease analysis demonstrates that the addition of ionic liquids alters the electrical properties of the lubricant, resulting in higher dielectric strength and conductivity of the grease. Secondly, electrical discharge test results indicate that the discharge behavior is significantly influenced by the EHL characteristics and lubricant properties. Meanwhile, electrical discharge induces film recession and fluctuation, primarily caused by Joule heating and localized pressure variations. Test results show that higher conductivity and viscosity lubricant can effectively reduce the recession of lubrication caused by electrical discharge. A correction factor was established for predicting lubrication under the electric field, and the calculated film thickness aligns well with the measured film thickness in full film lubrication. The comparison between corrected and measured film thickness further validates the discharge characteristics and mechanism of conductive grease.</div></div>","PeriodicalId":23238,"journal":{"name":"Tribology International","volume":"209 ","pages":"Article 110725"},"PeriodicalIF":6.1,"publicationDate":"2025-04-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143834176","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}

Under cyclic loading conditions, they are susceptible to fretting fatigue, which can lead to premature failure. Therefore, improving the accuracy of lifetime prediction under fretting fatigue is crucial. In dovetail joints, fretting conditions result in a complex stress-strain distribution on the contact surface, affecting the applicability of different failure criteria. This study examines the stress states across various models and evaluates the suitability of each criterion accordingly. The accuracy of crack initiation angle prediction for two types of dovetail joints is improved. The maximum principal stress serves as a reference for extreme stress, while the stress gradient describes the rate of change in stress. The combination of stress gradient and maximum principal stress provides a more comprehensive representation of stress distribution. The traditional Theory of Critical Distances (TCD) is unable to effectively address the complex stress distribution in stress concentration areas. To overcome this limitation, a Modified TCD (MTCD) is proposed, integrating the effects of stress gradients and maximum principal stress into the original TCD framework. The MTCD method significantly improves the accuracy of predicting the initiation lifetime of both dovetail joints compared to the traditional TCD method. This study not only enhances the understanding of fretting fatigue behavior in dovetail joints but also provides a reliable predictive tool for evaluating more complex models of dovetail joints.</div></div>","PeriodicalId":23238,"journal":{"name":"Tribology International","volume":"209 ","pages":"Article 110728"},"PeriodicalIF":6.1,"publicationDate":"2025-04-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143860449","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}

Driven by the goals of economic and social sustainability, we are committed to finding an ideal balance between these two seemingly opposing properties through molecular structure design and reinforcement optimization. On this foundation, we have innovatively integrated damage monitoring into the coating material. Herein, an advanced multifunctional waterborne polyurethane-based composite coating (BNC-SWPU) was constructed for the first time by innovatively combining self-healing, wear resistance and damage monitoring. These properties were conferred by a design strategy that combined modified boron nitride nanosheets/carbon quantum dots (BNON/CQD) hybrid fillers with multiple dynamic reversible bonds (disulfide and hydrogen bonds). BNON/CQD fillers synergistically enhanced the wear resistance of coatings through the interlayer slip of BNON and the nano-bearing-like structure exhibited by CQD at the sliding interface. Meanwhile, the composite coatings possessed excellent self-healing ability under both scratch and wear due to the easy migration of molecular chains and the capability of the dynamic bonds to break and reform in response to thermal stimuli. The composite coatings, due to the introduction of CQD with fluorescent properties, were endowed with an intense blue emission capability under UV light. Upon damage, emission intensity diminished but recovered post-self-healing. Consequently, this innovative design provides new ideas for the development of smart materials, while the multifunctionality it gives to composite coatings shows great potential for practical applications.</div></div>","PeriodicalId":23238,"journal":{"name":"Tribology International","volume":"209 ","pages":"Article 110723"},"PeriodicalIF":6.1,"publicationDate":"2025-04-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143844516","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 investigate the mixed thermal-visco-hyperelastic lubrication performance of water-lubricated rubber bearings (WLRBs) in deep-sea environment, this paper develops a mixed thermal-visco-hyperelastic hydrodynamic lubrication model (MTVHHLM). This model incorporates the effects of both the deep-sea high-pressure and low-temperature conditions, as well as localized temperature increases within the bearing, on the rubber material properties. In this study, the central fluid pressure distribution and temperature distribution predicted by the present model are validated by published experimental results, thereby confirming their accuracy. Furthermore, under the current simulation conditions, as specific pressure increases, the influence of seawater depth on the mixed thermal-visco-hyperelastic lubrication performance of WLRBs becomes more pronounced. As seawater depth increases, the rise in seawater pressure reduces fluid shear stress. However, this effect is partially offset by the decrease in ambient temperature. Consequently, the variations in friction coefficient and heat-flux caused by fluid shear with increasing seawater depth are relatively minor. The variation in viscoelastic dissipation and actual contact shear is the primary factor influencing the total friction coefficient and heat-flux as seawater depth increases. Furthermore, in deeper seawater environments, WLRBs can achieve a state closely resembling elastohydrodynamic lubrication at relatively low speeds. This study offers a valuable reference for the application of WLRBs in deep-sea environments.</div></div>","PeriodicalId":23238,"journal":{"name":"Tribology International","volume":"209 ","pages":"Article 110713"},"PeriodicalIF":6.1,"publicationDate":"2025-04-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143834175","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 findings demonstrate that the phase transition behaviour of 374RA at elevated temperatures significantly promotes the enrichment of MDIT on the surface of friction pairs, thereby substantially enhancing the lubricating performance. Specifically, the addition of MDIT reduces wear by 90 % and increases load capacity by 227.1 %. Through energy-dispersive spectroscopy (EDS) and quantum chemical calculations, the study confirms that the formation of physical and chemical adsorption layers on the friction surface is key to the improved performance, with the synergistic interaction between 374RA and MDIT playing a pivotal role.
