High toughening and low friction of novel bismaleimide composites with organic functionalized serpentine@Fe3O4

Tribological Performance Studies of Waterborne Polyurethane Coatings with Aligned Modified Graphene Oxide@Fe3O4

“…This may be attributed to the agglomerate in the 2 wt % GO@Fe 3 O 4 /WPU, so its ability to prevent microcrack propagation is drastically reduced. 46 The agglomerated GO@Fe 3 O 4 may hinder the formation of a continuous transfer film, resulting in increased wear debris on the wear surface.…”

“…Moreover, as shown in Figure e, when the amount of GO@Fe 3 O 4 is 2 wt %, it can be seen that the wear surface of the coating is very rough and accompanied by wear debris. This may be attributed to the agglomerate in the 2 wt % GO@Fe 3 O 4 /WPU, so its ability to prevent microcrack propagation is drastically reduced . The agglomerated GO@Fe 3 O 4 may hinder the formation of a continuous transfer film, resulting in increased wear debris on the wear surface.…”

Tribological Performance and Application of Antigorite as Lubrication Materials

“…Solid composites containing AMNP: effective improvement of the tribological properties of polytetrafluoroethylene (PTFE) or Al matrix composites is the key to prolong their service life and performance. Some research works on the evaluation of tribological performances of composite materials made by mixing AMNP with polymer or metal-base alloys has been carried out in the last decade [50,62,[68][69][70][71]73,[88][89][90] (Table 1, No.47 to 66). Sleptsova et al, (2009) found that the friction coefficient and wear of PTFE with ≤5% AMNP decreased by 10-15% and 95.6-99.8% compared with those without AMNP, as well as their rupture strength, elongation at rupture and modulus of elasticity at rupture were similar to that without AMNP [68].…”

“…Besides, it is interesting to note that the elastic modulus of the surface of the friction pair treated with AMNP does not show the same regularity as hardness and roughness (Table 1, No. [89][90][91][92][93][94][95][96][97][98]. In other words, the elastic modulus of the surface of the friction pair treated with AMNP is higher or lower than that of the one without AMNP.…”

“…The mechanistic studies have been carried out with either the assistance of surface composition and structure characterization of friction pairs, or the postulation from comprehensive experimental observations on antigorite Besides, it is interesting to note that the elastic modulus of the surface of the friction pair treated with AMNP does not show the same regularity as hardness and roughness (Table 1, No. [89][90][91][92][93][94][95][96][97][98]. In other words, the elastic modulus of the surface of the friction pair treated with AMNP is higher or lower than that of the one without AMNP.…”
