A finite-element-aided ultrasonic method for measuring central oil-film thickness in a roller-raceway tribo-pair
Springer Science and Business Media LLC - Tập 10 - Trang 944-962 - 2021
Pan Dou, Tonghai Wu, Zhaopeng Luo, Peiping Yang, Zhongxiao Peng, Min Yu, Tom Reddyhoff
Roller bearings support heavy loads by riding on an ultra-thin oil film (between the roller and raceway), the thickness of which is critical as it reflects the lubrication performance. Ultrasonic interfacial reflection, which facilitates the non-destructive measurement of oil-film thickness, has been widely studied. However, insufficient spatial resolution around the rolling line contact zone rema...... hiện toàn bộ
Does laser surface texturing really have a negative impact on the fatigue lifetime of mechanical components?
Springer Science and Business Media LLC - Tập 9 - Trang 1766-1775 - 2021
Chia-Jui Hsu, Andreas Stratmann, Simon Medina, Georg Jacobs, Frank Mücklich, Carsten Gachot
Laser surface texturing (LST) has been proven to improve the tribological performance of machine elements. The micro-scale patterns manufactured by LST may act as lubricant reservoirs, thus supplying oil when encountering insufficient lubrication. However, not many studies have investigated the use of LST in the boundary lubrication regime, likely due to concerns of higher contact stresses that ca...... hiện toàn bộ
How the fluorographene replaced graphene as nanoadditive for improving tribological performances of GTL-8 based lubricant oil
Springer Science and Business Media LLC - Tập 9 - Trang 488-501 - 2020
Xiaojing Ci, Wenjie Zhao, Jun Luo, Yangmin Wu, Tianhao Ge, Qunji Xue, Xiulei Gao, Zhiwen Fang
Fluorographene, a new alternative to graphene, it not only inherits the 2-dimensional (2D) layered structure and outstanding mechanical properties, but also possesses controllable C–F bonds. It is meaningful to reveal the evolution processes of the tribological behaviors from graphene to fluorographene. In this work, fluorinated reduced graphene oxide nanosheets (F–rGO) with different degree of fl...... hiện toàn bộ
Influence and optimization of swirler parameters on elbow wear of deep coal fluidization pipeline transportation system
Springer Science and Business Media LLC - - 2024
Shaodi Zhao, Jiusheng Bao, Shirong Ge, Zhongbin Wang, Yan Yin, Congguang Huang
Elbow wear is a major threat to the multiphase pipeline transportation industry, which has a negative impact on the stable operation of the transportation system. In order to find the wear reduction methods of elbows in the fluidization pipeline transportation system for 2000-meter-deep coal resources, the swirler was installed upstream of the elbows, and wear simulations and tests of three kinds ...... hiện toàn bộ
Eco-friendly polysaccharide coatings for antifouling and drag-reduction and potential application for marine devices
Springer Science and Business Media LLC - - Trang 1-19 - 2023
Hao Yang, Liguo Qin, Wenhui Zhao, Fagla Jules Mawignon, Hui Guo, Yongkang Wu, Yali Zhang, Guangneng Dong
Traditional antifouling agents usually have a certain toxic effect on marine environments and non-target organisms. In this study, Dictyophora indusiata polysaccharide (DIP) was applied as a natural antifouling surface modifier to prepare the surface coating for marine antifouling. Three DIP coatings were prepared: D. indusiata spore polysaccharide (DISP), D. indusiata volva polysaccharide (DIVP),...... hiện toàn bộ
Influence of a carbon-based tribofilm induced by the friction temperature on the tribological properties of impregnated graphite sliding against a cemented carbide
Springer Science and Business Media LLC - - 2021
Jun Zhao, Qingzhan Li, Shuangxi Li, Shicong Li, Guangyan Chen, Xinghua Liu, Yongyong He, Jianbin Luo
AbstractImpregnated graphite has attracted considerable attention and has been widely used as an ideal friction material in many fields. However, the influence of the friction temperature on its tribological properties has not been clearly studied; furthermore, the evolution mechanism of transferred tribofilm is unknown. In this study, the tribological properties o...... hiện toàn bộ
Wear monitoring method of water-lubricated polymer thrust bearing based on ultrasonic reflection coefficient amplitude spectrum
Springer Science and Business Media LLC - Tập 11 - Trang 685-703 - 2023
Changxiong Ning, Fei Hu, Wu Ouyang, Xinpin Yan, Dongling Xu
The water-lubricated thrust bearings of the marine rim-driven thruster (RDT) are usually composed of polymer composites, which are prone to serious wear under harsh working conditions. Ultrasonic is an excellent non-destructive monitoring technology, but polymer materials are characterized by viscoelasticity, heterogeneity, and large acoustic attenuation, making it challenging to extract ultrasoni...... hiện toàn bộ
Pin-on-disc study of dry sliding behavior of Co-free HVOF-coated disc tested against different friction materials
Springer Science and Business Media LLC - Tập 9 - Trang 1242-1258 - 2021
Matteo Federici, Cinzia Menapace, Alessandro Mancini, Giovanni Straffelini, Stefano Gialanella
The dry sliding behavior of three commercial friction materials (codenamed FM1, FM2, and FM3) tested against a Co-free cermet coating produced by high-velocity oxy-fuel (HVOF) on gray cast-iron discs is investigated. FM1 is a conventional low-metallic friction material, FM2 is developed for using against HVOF-coated discs, and FM3 is a Cu-free friction material with a low content of abrasives and ...... hiện toàn bộ
Surface modification of YS-20 with polydopamine for improving the tribological properties of polyimide composites
Springer Science and Business Media LLC - Tập 10 - Trang 411-421 - 2021
Liangfei Wu, Zhaozhu Zhang, Mingming Yang, Junya Yuan, Peilong Li, Zujun Chen, Xuehu Men
Recently, great effort has been devoted to prepare various reinforce fillers to improve polymer performances, but ignoring the importance of raw polymer powders which are indispensable parts of hot-pressed polymer composites. Herein, we engineer raw polyimide (PI) powders with the assistance of polydopamine (PDA) in aqueous solutions. After the modification, polymer powders change from hydrophobic...... hiện toàn bộ
Nanotribological studies using nanoparticle manipulation: Principles and application to structural lubricity
Springer Science and Business Media LLC - Tập 2 - Trang 114-139 - 2014
Dirk Dietzel, Udo D. Schwarz, André Schirmeisen
The term “structural lubricity” denotes a fundamental concept where the friction between two atomically flat surfaces is reduced due to lattice mismatch at the interface. Under favorable circumstances, its effect may cause a contact to experience ultra-low friction, which is why it is also referred to as “superlubricity”. While the basic principle is intriguingly simple, the experimental analysis ...... hiện toàn bộ
