Summary: Friction coefficients and wear rates of PLA-stainless steel pair were investigated using four aprotic imidazolium and one bio-based protic ammonium ionic liquid (IL) lubricants. The ILs greatly reduced the friction coefficient and prevented wear in the rotational pin-on-disk test. The halogen-free protic ammonium IL exhibited the best performance in the linear reciprocating sliding test.

Summary: This study investigated the vacuum tribological behaviors of nickel-matrix/Ag/(Ca, Ba)F2/graphite composites, and found that the addition of 2 wt% graphite significantly improved the frictional properties and reduced the wear rate over the entire testing temperature range in vacuum. The synergistic effects of solid lubricants were believed to contribute to the enhanced tribological properties of the composites.

Summary: In this study, a bioinspired sharkskin mask was used to print a convex texture of Cr3C2 reinforced Ni3Al matrix composite, which exhibited outstanding high-temperature strength and wear resistance. The synergistic lubrication behavior between the convex texture and Ti3SiC2/MoS2 lubricants was explored, and the composite films showed long wear life and excellent stability in friction. The improvement in friction coefficient can be attributed to the storage function of the sharkskin convex texture and the formation of continuous transfer films.

Summary: A novel ethanol-water Tris buffer system was developed to fabricate a hydrophilic polydopamine (PDA) protective layer on the surface of polytetrafluoro-wax (PFW). The resulting PFW@PDA displayed excellent dispersion stability in an aqueous slurry, and paper-based composite films were obtained by removing water from the slurry. The composite film exhibited excellent water resistance, thermal stability, and mechanical properties with reduced friction coefficient and wear rate.

Summary: The synthesis of MAX-based composites using Ti3SiC2 and non-stoichiometric Ti/SiC powders was conducted via FAST/SPS in vacuum at temperatures of 1350-1450 degrees C. The microstructure and phase composition of the composites were analyzed using XRD, LM, SEM, and EDS. The composites exhibited self-lubricating effects during sliding and near-zero wear at high temperatures. The hardness and fracture toughness of the composites were determined, with Ti3SiC2 being the dominant phase.

Summary: Introduction of self-lubricating and conductive Ti3SiC2 particles into soft copper significantly enhances its wear resistance without sacrificing electrical conductivity. Homogeneous dense composites can be obtained when the Ti3SiC2 content is below 20 vol%, while higher content leads to a porous structure. The composites with 20 vol% Ti3SiC2 content exhibit the lowest wear rate of 3.135 x 10-5 mm3 N-1 m-1 and a conductivity of 63% IACS. The introduction of Ti3SiC2 also increases the hardness of the composite by 98% compared to copper, up to 121 HV.

Summary: Fe-based self-lubricating composites with SiC particles as precursors were produced via powder injection moulding. Different SiC polytypes did not significantly affect the lubricant structure and properties of the composites. However, the composites exhibited lubricity, low friction coefficient, and high wear resistance due to the formation of a highly disordered graphite-rich tribolayer, even under oil-lubricated conditions.

Summary: Ni3Al matrix self-lubricating composites containing Sn-Ag-Cu and Ti3SiC2 were synthesized, and their tribological behavior and wear-triggered self-healing properties were investigated through dry sliding friction tests from 20 to 800 degrees C. The results show that the tribological behaviors and self-healing properties of the composites are strongly dependent on the testing temperature. The best self-healing effect was observed at 400 degrees C.

Summary: Ti3SiC2/Cu composite with wide temperature range lubricating properties was successfully prepared by Spark Plasma Sintering process. The microstructure, composition, mechanical properties, and friction-wear behavior of the composite were investigated. The results showed that TSC-Cu had higher friction coefficient and lower wear rate compared to polycrystalline Ti3SiC2, indicating its potential application in mechanical equipment components.

Summary: This paper investigates the fabrication of Cu-Ni-Al/Gr solid-lubricating composites with 2.5-10 wt% graphite for high temperature applications. The effects of graphite contents on tribological behavior from room temperature to 500°C were thoroughly examined. The results indicate that the addition of graphite significantly improves tribological properties, but no further enhancement is observed when graphite reaches 7.5-10 wt%. The excellent tribological performance at 25-500°C is attributed to the synergistic effects of self-lubrication provided by graphite lubricant and the tribo-oxide layer formed during sliding.

The system successfully characterizes the mechanical properties of fine copper wires and the results are consistent with known values. The proposed 3D printed tensile testing system offers an accessible and cost-efficient method for accurate mechanical characterization of small-sized specimens.
