“…In recent years, there have been considerable interests in nanoparticles on account of their distinct advantages over microcomposites because that the performance improvement is often acquired at relatively low concentration of the nano-fillers [7]. Many researchers have found that a great variety of nano-inorganic reinforcements, such as metal oxidation nanoparticles, silicon compounds, carbon nanotubes (CNTs) and some other nanoparticles [8][9][10][11][12][13][14][15][16][17][18][19] could largely improve the tribological properties of polymers as well as the mechanical properties. Li et al [8] investigated the tribological characteristics of polytetrafluoroethylene (PTFE) composites filled with zinc oxide (ZnO) nanoparticles and found that the anti-wear property of the polymer could be improved without deterioration of the friction coefficient.…”

“…Lai et al [12] studied the effect of SiO 2 size on the friction and wear behaviors of polyimide (PI)/SiO 2 hybrids by sol-gel processing and found that the friction coefficient and wear rate of the PI hybrids firstly decreased and then increased with the increasing size of SiO 2 . By introducing small amounts of CNTs, the mechanical properties, electrical properties and the tribological properties of composite materials can be improved tremendously [13][14][15][16][17][18][19]. However, few reports have been available on the tribological behaviors of organic nanoparticles modified polymers.…”

The mechanism involved in the codeposition of carbon nanotubes (CNTs) with copper from an acid copper sulfate bath was investigated. Multiwalled carbon nanotubes (MWCNTs) were employed and dispersed using polyacrylic acid. To determine the influence of the fibrous shape of the MWCNTs, codeposition was also carried out using copper and granular carbon black (CB). The effect of the polyacrylic acid on the dispersibility of MWCNTs and CB in the plating baths and the electrodeposition behavior of copper was investigated. In addition, the relationship between the initial MWCNT or CB concentration in the plating bath and that in the composite films was evaluated and the results are discussed based on the two-step adsorption model of Guglielmi. It was found that although for low MWCNT concentrations in the plating bath, this model could adequately explain the codeposition behavior, at higher concentrations, the MWCNT content in the deposit was larger than expected. It is suggested that the increased MWCNT content is related to the fibrous shape of the MWCNTs. Carbon nanotubes (CNTs) 1,2 have excellent mechanical characteristics, such as high tensile strength and elastic modulus, and exhibit high thermal and electrical conductivities. Recently, the fabrication of various metal/CNT composites, which are expected to be promising functional materials, has been attempted using plating techniques, and in particular, composite plating. 3-11The composite plating technique that was first reported by Sauter 12 can produce metal films with a variety of functions, and has thus been widely researched for the fabrication of functional materials. However, practical applications of this technology have been limited to a few cases. Therefore, to increase the range of applications of CNT and other composite plating techniques, elucidation of the mechanism involved in the codeposition of particles with a metal is very important. There have been several reports on the kinetics and mechanism involved during composite plating using electrodeposition. Snaith and Groves first proposed the occurrence of mechanical bonding between a metal matrix and ceramic particles. 13 Guglielmi developed a rate equation based on a two-step adsorption model.14 Celis and Roos proposed that the particle codeposition rate is determined by the reduction rate of metal ions that are adsorbed on the particles. 15 Forester reported a codeposition mechanism based on the zeta potential. 16 Hayashi et al. proposed that the amount of metal ions adsorbed on particles has an important influence on the codeposition behavior.17 Roos and coworkers also developed a mathematical model for codeposition. 18,19 In all of these studies on the codeposition mechanism, hydrophilic granular particles such as alumina were used without dispersing agents. In contrast, multiwalled carbon nanotubes (MWCNTs) are hydrophobic and have fibrous shapes, and may therefore be expected to behave differently during the codeposition process. To clarify the mechanism involved in the codeposition of MWC...

Co-W alloy/multiwalled carbon nanotube (MWCNT) composite films were fabricated using an electrodeposition technique and their microstructures were characterized. A citrate bath was used as the Co-W alloy/MWCNT composite plating bath. A compact Co-W alloy/MWCNT composite film having uniform distribution of MWCNTs without cracks was electrodeposited by adjusting the pH and current density. Frictional properties of the Co-W alloy/MWCNT composite film were evaluated using a ball-on-disk method at room temperature as well as at elevated temperatures (∼ 300 • C) without any lubricant. The coefficient of friction of the Co-W alloy/MWCNT composite film was clearly lower than that of a Co-W alloy film with the same tungsten content at room temperature. The coefficient of friction of the Co-W alloy/MWCNT composite film increased with increasing temperature. However, the coefficient of friction of the Co-W alloy/MWCNT composite film was lower than that of a Co-W alloy film with the same tungsten content at elevated temperatures. © 2013 The Electrochemical Society.

Published September 25, 2013 Due to their high hardness, wear resistance, 1 and high corrosion resistance, 2,3 Co-W alloy plating films are expected to be a substitute for chromium plating films, which are formed in an environmentally hazardous process using hexavalent chromium. Due to their superior mechanical properties, very high thermal conductivity, and excellent solid lubricity, carbon nanotubes (CNT) 33,34 are expected to be used as fillers for functional composite materials. Consequently, the formation of metal/CNT composites has been studied by various methods including plating techniques for various applications. Fabrication of metal/CNT composite films for use in tribological applications has also been extensively researched using electrodeposition [35][36][37] and electroless deposition. [38][39][40] These studies demonstrated that metal/CNT composite films show lower apparent coefficients of friction compared to simple metal films without CNTs at room temperature.Co-W alloy/CNT composite films are thus a potential candidate to replace chromium plating films. However, there have been no reports on Co-W alloy/CNT composite films so far. In this study, Co-W alloy/CNT composite films were fabricated using an electrodeposition technique. The tribological properties of the Co-W alloy/MWCNT composite film were evaluated at room temperature as well as at high temperatures. ExperimentalThe CNTs used in the present study are commercially available vapor-grown MWCNTs (Showa Denko Co. Ltd.), formed via catalyst-assisted CVD 41 and heat treated at 2800 Na 3 C 6 H 5 O 7 · 2H 2 O) was used as the base alloy bath. 42 The MWCNTs did not disperse uniformly in the base bath; therefore, a homogeneous dispersion of MWCNTs was achieved by the addition of a polyacrylic acid (mean molecular weight 5000; PA5000) dispersant [43][44][45] to the b...
