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}

This study investigates the synergistic anti-wear and friction-reducing properties and mechanisms of water-soluble block polyether 374RA, known for its temperature-responsive characteristics, in combination with two phosphate ester additives: phenol polyoxyethylene ether phosphate (PHB14) and isotridecyl phosphate (MDIT). 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.

This investigation addresses this exigency by using a new tool during FSP. This study explores the use of FSP to enhance the surface properties of AA5754 aluminum alloy by incorporating ZrO<sub>2</sub> and hBN reinforcement powders. The experiments were performed using two distinct tool geometries – a Conventional Cylindrical Pin (CCP) tool and a modified Protruding Cylindrical Pin (PCP) tool, to assess the effect of tool design on particle distribution and microstructural refinement. Resulted revealed that the PCP tool, featuring a protrusion on the stirring pin, was developed to improve the quality of surface appearance. Moreover, it was found that utilizing a PCP tool resulted in the highest level of uniformity in particle dispersion across the matrix. The results also demonstrated that the highest shear strength was recorded for the sample FSPed with the PCP tool (193 MPa) as compared to the sample FSPed with the CCP tool (171 MPa). The higher shear strength is attributed to the significantly improved dissemination of hBN and ZrO<sub>2</sub> particles within the matrix and further refinement of grains in the stir zone. From the results, it was also observed that a tool with a protrusion on the stirring pin had better material flow and higher resistance to corrosion and wear than a tool with a regular pin profile.</div></div>","PeriodicalId":23238,"journal":{"name":"Tribology International","volume":"210 ","pages":"Article 110720"},"PeriodicalIF":6.1,"publicationDate":"2025-04-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143934604","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}

This study investigates the fretting fatigue behavior of aluminum alloy–steel connections fastened by swage-locking pins through experiments and numerical analysis. It involved fatigue experiments under tension loading, fretting wear and fatigue analyses, followed by fatigue crack initiation prediction. Results show that the contact surface of clamped plates can be divided into the stick, slip, and open zones, with fretting wear occurring within the slip zone of aluminum alloy plate. Fretting fatigue cracks typically initiate within the slip zone near the stick-slip boundary, specifically at wear scars edges. A finite element model was developed to analyze contact status and stress states of test connections, with the friction coefficient at the aluminum alloy-steel interface optimized based on measured stick zone sizes. Results show the fatigue crack initiation of test connections is predominantly influenced by tensile stresses. Consequently, the SWT multiaxial fatigue criterion, combined with the critical plane method, can be used to predict crack initiation.
