Mechanism of Nanoparticles Functioning and Effects in Machining Processes: A Review

“…A variety of mechanisms have been explored to explain the improvement in lubricity of nanofluids including formation of tribo-film [16][17][18][19][20], ball bearing effect [21][22][23], mending effect [24] and polishing effect [25]. Furthermore, Lee et al [26] performed the experiment on disc with disc type tester and delineated two effects: (a) direct effect i.e., sliding/rolling/filming, and (b) surface enhancement effect, i.e., mending/polishing of nanofluids, primarily responsible for improvement in machining performances.…”

Adhesion and Friction of Polymers

“…88 The inhibitive action of fullerenes and carbon nanomaterials with respect to thermal and thermal-oxidative degradation of polymer materials has been studied and is still under intensive study. 89,90 Fullerenes are electrophilic being the active acceptors of electrons. They tend to accept nucleophilic reagents and also hydrogen, free-radical and carbenoidal particles.…”

Estudio del Poder Lubricante del Aceite de Ajonjolí con Adición de Nanopartículas de Cobre

“…A su vez, la concentración de esfuerzos compresivos asociada con la alta presión de contacto, puede ser reducida por la acción de muchas NPs soportando las fuerzas compresivas, hecho que mejora el desempeño del aceite en condiciones de lubricación a extrema presión (Ginzburg et al, 2002;Israelachvili et al, 2005;Liu et al, 2004;Peng et al, 2009;Rapoport et al, 2003;Rapoport et al, 2002;Tao et al, 1996).
