Various MoS2-, WS2- and C-Based Micro- and Nanoparticles in Boundary Lubrication

Effect of the type, size and concentration of solid lubricants on the tribological properties of the polymer PEEK

“…Based on the XPS results of our transfer films the oxidation rate of the MoS₂ was lower than that of the WS₂, which was also observed in other literature [33].…”

Boundary lubrication: Influence of the size and structure of inorganic fullerene-like MoS2 nanoparticles on friction and wear reduction

“…In the light of these results, the use of perfectly engineered fullerene-like nanoparticles seems questionable. A recent study by Kogovsek et al [26] furthermore suggests that the chemical nature of the additives affects friction reduction much more significantly than their size or shape, as similar tribological test results were obtained for many different kinds of MoS 2 micro-and nanoparticles (nanotubes, 2 mm platelets and 10 mm platelets). To verify these hypotheses, the tribological performances of bulk MoS 2 particles were compared to those of the poorly crystalline IF-MoS 2 tested before.…”

2D-nanomaterials for controlling friction and wear at interfaces

“…Further wear loss experiments indicated the MoS 2 and WS 2 particles had the best wear reduction followed by the carbon nanotubes while the graphite platelets offered the least wear resistance. In this case, there was no dependence of the friction coefficients on size or morphology found, but it is noted that smaller particles have an intrinsic advantage in the ability to be more easily dispersed in the oil lubricant [78].…”
