“…The increased normal load to 6 N slightly decreases the mean friction coefficient of the epoxy to about 0.61. The sliding of a steel counterpart on a polymer can cause localized softening or melting of the polymer so that the molten materials can be transferred onto the surface of the counterpart to form a transfer layer [18][19][20]. The transferred polymer layer can reduce the friction coefficient by changing the rubbing mode from the metal-on-polymer to the polymer-on-polymer during the sliding [21][22][23][24][25].…”

Tribological properties of short carbon fibers reinforced epoxy composites

et al. 2014

Short carbon fiber (SCF) reinforced epoxy composites with different SCF contents were developed to investigate their tribological properties. The friction coefficient and wear of the epoxy composites slid in a circular path against a steel pin inclined at 45° to a vertical axis and a steel ball significantly decreased with increased SCF content due to the solid lubricating effect of SCFs along with the improved mechanical strength of the composites. The scanning electron microscope (SEM) observation showed that the epoxy composites had less sensitive to surface fatigue caused by the repeated sliding of the counterparts than the epoxy. The tribological results clearly showed that the incorporation of SCFs was an effective way to improve the tribological properties of the epoxy composites.

“…This fact was corroborated by Raman laser spectroscopy. These authors considered that this phenomenon occurred as consequence of large flash temperatures at the contact points between the tribopairs and used the equation proposed by Ashby et al [45] for evaluating this temperature, which resulted in a value of ΔT $300 1C.…”

is an open access repository that collects the work of Arts et Métiers ParisTech researchers and makes it freely available over the web where possible. Quantitative EPMA analysis carried out on the coated sample cross-section coupled with nanoindentation techniques allowed the identification of the coated system architecture as composed of 4 main layers, with distinct mechanical properties, on top of the aluminium substrate: DLC (a:C-H chromium dopped layer and graded layer of CrC), a newly formed graded layer of CNiPCr, product of the interdifusion during PVD processing, and the NiP coating. The change in the elastic modulus with penetration depth was described by means of an original approach that was developed for its specific application to multilayer coatings.

“…As found in Figure 5A, the friction coefficient of the nanocomposite film co-incorporated with 4 wt% MWCNTs and 2 wt% SiO 2 -MPs is about 0.591 that is higher than that of the PMMA film, indicating that the co-incorporation of MWCNTs and SiO 2 -MPs increases the friction of the nanocomposite film. The incorporation of MWCNTs should reduce the friction of the nanocomposite film due to the solid lubricating effect of the MWCNTs [6,[11][12][13][14][15][16][17]. However, the increased friction of the nanocomposite film ( Figure 5A) clearly shows that the solid lubricating effect of the MWCNTs on the friction of the nanocomposite film is not significant in this study.…”

“…However, the increased friction of the nanocomposite film ( Figure 5A) clearly shows that the solid lubricating effect of the MWCNTs on the friction of the nanocomposite film is not significant in this study. In addition, the surface wear can release filler aggregates to the interface between the steel ball and nanocomposite film during the sliding and reduce the friction of the nanocomposite film via the free-rolling of the aggregates [6,[11][12][13][14][15][16][17]. The increased friction of the nanocomposite film associated with the co-incorporation of MWCNTs and SiO 2 -MPs clearly indicates that the fillers do not have the freerolling effect on the friction of the nanocomposite film.…”

“…Figure 7A and B clearly confirm that the repeated sliding of the steel ball on the PMMA film generates a significant wear on the surface. Abrasive lines on the wear track of the PMMA film ( Figure 7B) is indicative of the abrasive wear of the PMMA film [16,17]. The surface wear of the PMMA film generates wear debris during the sliding and the repeated sliding of the steel ball compacts the debris to form localized tribolayers on the wear track.…”

Abstract Multiwalled carbon nanotubes (MWCNTs) and silicon dioxide microparticles (SiO2-MPs) were co-incorporated in poly(methyl methacrylate) (PMMA) matrices to form PMMA/MWCNT-SiO2-MP nanocomposite films. The SiO2-MP content in the nanocomposite films was varied at a fixed MWCNT content of 4 wt% to investigate the effect of SiO2-MP content on the electrical and tribological properties of the PMMA/MWCNT-SiO2-MP nanocomposite films. The co-incorporation of MWCNTs and SiO2-MPs dramatically lowered the electrical resistance of the nanocomposite films compared to that of the PMMA film, while higher fractions of SiO2-MPs more effectively promoted the decrease in the electrical resistance of the nanocomposite films by improving the conductive networks formed by the MWCNTs in the PMMA matrices. Although the friction of the nanocomposite films significantly increased with increased SiO2-MP content due to the promoted mechanical interlocking between the surface asperities of two mating surfaces, the wear of the nanocomposite films was much less severe than that of the PMMA film during ball-on-disc tribological tests.
