Effect of natural attapulgite powders as lubrication additive on the friction and wear performance of a steel tribo-pair

Lubrication performance of MoS2 and SiO2 nanoparticles as lubricant additives in magnesium alloy-steel contacts

“…When the applied load is low, the energy produced by sliding friction is too low to impel tribochemistry reaction between the nano-MoS 2 and magnesium surface. As the applied load increases, more energy will be supplied, the additive nanoparticles become easier to react with the metal friction pair, thus accelerate the formation of the tribo-film, leading to friction-reducing [29]. The friction behavior of spherical nano-SiO 2 was found to be quite different from the MoS 2 platelets under the same test conditions.…”

The purification and tribological property of the synthetic magnesium silicate hydroxide modified by oleic acid

“…With the addition of MMSH, besides iron oxides and Fe 3 C, FeOOH at 711.6 eV is also found on the worn surface. The C1s peak could be decomposed into 3 peaks at 287.3, 284.3, and 283.6 eV, suggesting the existence of carbon‐oxygen bond, graphite, and Fe 3 C . The C1s on the worn surface lubricated by the MMSH‐containing oil has 2 more peaks at 288.0 and 285.4 eV, which indicates that C element also exists in the form of organic compounds.…”

Recent progress in dispersion of palygorskite crystal bundles for nanocomposites

“…Undoubtedly, the contribution of bulk crystal bundles to performance is far away lower than that of individual nanorods. The nanoscale Pal is potential to be applied to develop lubricant additive (Nan et al, 2014), smart materials (Peng et al, 2011;Jin et al, 2014), biomaterials (S. Han et al, 2014), plastic , rubber (Wang and Chen, 2013), tissue engineering materials , superhydrophobic coating , and so on. The special 1D nanoscale feature, excellent surface compatibility, and mechanical/ thermal stability of Pal render it advantageous as a filler of polymer materials.…”
