The matrix is independent of loading conditions, allowing it to be precomputed and stored for efficient reuse.

The fabricated surface demonstrated an ultra-low coefficient of friction and a significantly reduced wear rate. The underlying mechanism involves localized contact behavior creating a pressure differential that overcomes capillary forces, triggering on-demand lubricant release from the microchannels. The influence of laser processing parameters (i.e., scanning path, number of scans, and laser power) on surface microhardness and oil storage capacity under different loading conditions was investigated. Results showed that laser power predominantly affected the hardness and wear resistance of the micro-/nanostructures, while the scanning path and number of scans jointly enhanced self-lubricating capability. A multiphase interface self-lubrication and wear evolution model was established to explain the on-demand oil-release behavior.

This study proposes a novel strategy to utilize red mud as a filler in copper-free resin-based brake composites, aiming to replace environmentally problematic and costly copper. This approach not only offers a pathway towards copper-free brake composites but also presents a potential solution for the eco-friendly disposal of red mud. The effects of red mud content on the physical properties, mechanical properties, and friction-wear performance of the composites were systematically investigated, coupled with a comprehensive analysis of the wear mechanisms. Results indicate that incorporating an appropriate amount of red mud enhances the density, hardness, and impact strength of the composites. Crucially, it effectively improves the friction coefficient at medium to high temperatures, mitigating thermal fade. While density and hardness increased proportionally with red mud content, impact strength exhibited a complex non-linear trend, initially decreasing, then increasing, before decreasing again. The composite containing 35 wt% red mud demonstrated the most favorable overall friction-wear performance. An optimized formulation was derived using Response Surface Methodology (RSM): 18 wt% phenolic resin, 5 wt% bamboo fiber, 15 wt% alumina, 39 wt% red mud, 3 wt% graphite, 5 wt% nitrile rubber powder, and 15 wt% barium sulfate. This formulation maintained a stable friction coefficient between 0.48 and 0.50 across a test temperature range of 100 ∼ 350 °C.

This study comprehensively considers bidirectional fluid–structure–thermal interaction (FSTI), pressure and temperature induced elastic deformation, thermo-viscous effects, and asperity elasto-plastic contact, and, for the first time, incorporates adhesive/abrasive wear mechanisms and the transient dynamics of an inclined piston–slipper assembly into the hydrodynamic (HD) lubrication process. A transient mixed thermo-elastohydrodynamic lubrication wear-coupled model (MTEHD-W) is established. The accuracy of the model is validated by comparing leakage flow rate and energy loss predictions from the MTEHD-W model, the HD model, and analytical solutions under identical operating and structural parameters. The effects of different operating conditions and sealing band widths on leakage flow rate, energy loss, and lubrication–wear coupled characteristics are analyzed. The results indicate that the deformation, oil film thickness, pressure, and temperature distributions predicted by the MTEHD-W model agree well with literature data and experimental measurements.

The layer exhibits a unique \"anomalous grain gradient–nano dislocation architecture\" accompanied by carbon supersaturation. While LQ produces a hardened layer reaching 800 μm in depth, thermal boundary effects lead to anomalous grain coarsening at the surface (surface martensite: 2.74 μm vs. subsurface: 1.58 μm). USRP effectively counteracts this through high-frequency dynamic strain, implanting a high-density nano-dislocation network into coarse martensite. This results in an exceptional nanohardness exceeding 10 GPa, challenging the classical \"coarse-grain softening\" paradigm. The wear volume is reduced by 74.4 %, attributed to three synergistic mechanisms: an ultra-high strength barrier (combining nano-dislocation cell pinning and carbon-supersaturated martensite) that confines plastic deformation to sub-micron depths, suppressing material loss at its source; a hard gradient-supported tribo-oxide layer reducing friction and preventing direct metallic contact; and a wear-adaptive response involving dislocation-cell-catalyzed martensite nanonization and stress-induced ω phase transformation, establishing a self-reinforcing cycle of \"damage→nanonization/phase transformation→hardening\". These mechanisms achieve profound coupling through a \"pre-engineered gradient–hard substrate-supported oxide formation–dynamic adaptive response\" framework.
