“…In contrast, the friction coefficient of the Ni-P alloy-MWCNT composite films decreased rapidly at an early stage and reached a steady value, indicating solid lubricity caused by the intrinsic solid lubricity of the MWCNTs. 20,21 The friction coefficient of the Ni-P alloy-1.2 mass % MWCNT composite film was higher than that of the Ni-P alloy-0.7 mass % MWCNT composite film and the Ni-P alloy-0.9 mass % MWCNT composite film. This trend is different from that of the paper by Chen et al in that the friction coefficient decreased with increasing MWCNT content in the Ni-P MWCNT composite film.…”

Ni-P alloy-multiwalled carbon nanotube ͑MWCNT͒ composite films were fabricated by an electrodeposition technique, and their microstructure, hardness, and frictional properties were analyzed. Ni-P alloy-MWCNT composite films containing 20-22 atom % P and 0.7-1.2 mass % MWCNTs were electrodeposited from a composite plating bath. MWCNTs were embedded relatively uniformly in the Ni-P alloy matrix. The hardness of the composite films was higher than that of the Ni-P alloy films, both before and after heat-treatment, and the friction coefficient of the composite films was lower than that of the Ni-P alloy films. Carbon nanotubes ͑CNTs͒1,2 have excellent mechanical characteristics, such as high tensile strength and high elastic modulus, as well as high thermal and electrical conductivity. Therefore, research into practical applications of CNTs, such as resin-CNT, ceramic-CNT, and metal-CNT composites, has been actively pursued.3-5 Recently, the fabrication of metal-CNT composites has been attempted using an electrodeposition technique. 6,7 The present authors and others have also reported the fabrication and properties of electrodeposited metal-CNT composite films, such as Cu-CNT 8,9 and Ni-CNT. [10][11][12] However, fabrication of CNT composite films by an electroless plating technique has also been reported. [13][14][15][16][17] Li et al. reported the friction and wear behavior of Ni-P alloy-CNT composite coatings;13 the wear resistance and friction coefficient of the composite coating were lower than those of the Ni-P coating. Yang et al. reported that the corrosion resistance of the Ni-P alloy-CNT composite coating was higher than that of the Ni-P coating.14 Therefore, Ni-P alloy-CNT composite coatings are useful for practical applications, but no research on the fabrication of such coatings by electrodeposition has been reported. Electroless plating has several advantages over electrodeposition, such as the ability to produce a uniform film thickness and the capability of coating the insulator. Unfortunately, electroless plating also has several disadvantages, such as a chemically unstable plating bath and a relatively high temperature required to increase deposition speed. Coating mechanical components requires high productivity and low cost. So, we investigated the fabrication of Ni-P alloy-CNT composite coatings by electrodeposition.In the present study, Ni-P alloy-multiwalled carbon nanotube ͑MWCNT͒ composite films were fabricated using an electrodeposition technique, and the microstructure and characteristics of the composite films were investigated. Commercially available MWCNTs were used without pretreatment. ExperimentalCommercially available ͑Showa Denko Co., Ltd.͒ vapor-grown MWCNTs were used in the present study, obtained via catalystassisted chemical vapor deposition and heat-treated at 2800°C in Ar for 30 min. The MWCNTs were typically 100-200 nm in diameter and 20 m long. A Ni-P alloy plating bath ͑1 M NiSO 4 ·6H 2 O + 0.2 M NiCl 2 ·6H 2 O + 0.5 M H 3 BO 3 + 1 M H 3 PO 3 + 0.5 M C 6 H 5 Na 3 O 7 ͒ w...

“…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.…”

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.

Carbon nanotubes (CNTs) have solid lubricity due to their unique structure and as such, CNT composites are also expected to exhibit superior tribological properties. In this study, Co/CNT composite films were fabricated using a composite electrodeposition technique and their tribological properties were investigated. Three different sizes of multiwalled carbon nanotubes (MWCNTs) were used as CNTs. The microstructures of the composite films were examined using scanning electron microscopy. Frictional and wear properties were examined using a ball-on-disk method without any lubricants at room temperature and at high temperatures (100-500 °C). The Co/MWCNT composite films had lower coefficients of friction than a cobalt film at room temperature. In contrast, the coefficients of friction of the Co/MWCNT composite film at high temperature became higher than that at room temperature and slightly lower than that of a cobalt film.
