Water-lubricating bearings made of polymer-matrix composites have provided a new approach to prolong the service lifetime key component in marine propulsion system. However, it was still crucial find convenient and effective material manufacture water-lubricating bearing with ultralow friction. Herein, kind polyetheretherketone (PEEK) composite coefficient friction (COF), high mechanical strength thermal stability has been developed. An 80.7% decrease COF PEEK achieved by incorporating...
The design and development of self-lubricating materials aid in enhancing the tribological performance prolonging service life aero spherical plain bearings. Herein, monodisperse hollow mesoporous carbon nanospheres (HMCNs) with thin shell thickness uniform particle size were synthesized. Afterward, oil-containing nanocapsules (Oil@HMCNs) obtained by impregnation method, which was an innovative approach to prepare nanoscale capsules. Oil@HMCNs monodispersed, oil content rate could reach 45...
Understanding the collapse mechanisms of shallow, multi-layered, weakly cemented overburden is key to safe and efficient coal mining in central western China. Hence, we conducted a meter-scale similar physical model experiment using high-resolution digital speckle technology replicate deformation failure patterns shallowly buried, under activities, determine initiation, development, stability water-conducting fractures. Additionally, site-scale numerical was developed allow for examination...
Abstract When conducting retreat mining in segmented coal pillars, the dynamic evolution of stress and overlying strata structure is more complex than conventional working faces due to influence adjacent faces. Understanding mastering patterns after pillar essential for guiding safe recovery resources under similar conditions. Through statistical analysis types residual techniques, current research status system China has been summarized. Based on safety technology multi-type at Zhaogu No.2...
When the collapse column of overburden is disturbed by working face, grain loss in karst occurs dissolution and corrosion groundwater, thereby inducing water inrush disaster. The test samples are prepared based on fractal theory Talbol grading theory, seepage evolution law fractured rock under triaxial stress studied, employing equipment. Besides, mechanics model broken established calculated COMSOL Multiphysics, water-conducting channel mass condition further elucidated. research results...
In this study, SiO2 containing PAO6 microcapsules were endowed with surface active groups by polydopamine (PSPMS). Then the modified in situ grafted into phenolic resin (PF@PSPMS) to control dispersion and bonding high viscosity resin. Further, tribological properties of PF coating prepared liner analyzed. The results show that life PF@PSPMS-coating is 73 times longer than PF-coating, friction coefficient (COF) reduced 78%. Meanwhiles COF corresponding from 0.11 0.06, wear amount 64.07 μm...
Abstract The development and design of fillers aid in improving the tribological performances friction materials. Herein, effects aspect ratio mullite whisker on properties were studied. Mullite whiskers prepared by sol–gel process was controlled introducing aluminum fluoride (AlF 3 ). increased significantly at first then decreased with increasing contents AlF . experimental results show that higher stabilized coefficient while wear rate. In addition, composite grown excessive (20%)...
Abstract In order to improving the reliability and service life of polytetrafluoroethylene (PTFE) composites. Micro nickel‐titanium shape memory alloy (NiTi) particles were incorporated with PTFE powder develop composites by using filling modification technology. Herein, 25 kinds different contents micro NiTi prepared, which tribological compressive creep properties investigated in detail considering factors such as content (0, 10, 20, 30, 40, 50 wt%), cold‐pressed pressure(10, MPa), tested...
Zeolitic imidazolate frameworks (ZIFs) are ideal host materials in the adsorption and storage of lubricating oil due to their intrinsic features high porosity, uniform pore size, interconnected interior space, but they much less exploited oil-containing self-lubricating areas. Herein, an ultrahigh surface area cobalt-based ZIF material (ZIF-67) with periodic microporous channels is synthesized successfully introduced as oil-nanocontainer embedding UHMWPE matrix. The constructed composites...
