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...

“…On the other hand, high temperatures may damage the unique structure of CNTs and cause reaction between metallic matrices and CNTs [21]. As a result, detailed investigations on nanostructured metal-CNT composites have not been well conducted so far [11,22]. In the present study, nanostructured Cu-CNT composites were fabricated using a combination of ball milling, powder consolidation and high-pressure torsion (HPT) at room temperature, and microstructures and mechanical properties were characterized.…”

“…2 (a) and (b) presents the SEM image of the Ni(OH) 2 /CNTs nanocomposite. There are no obvious aggregations of Ni(OH) 2 and just some micrometer-long CNTs are randomly entangled to form a uniform three-dimension interconnected porous network structure [12][13]. At the same time some very little particles still can be found setting onto the surfaces of CNTs, although it is not very clear due to their even smaller size after more careful observation.…”

The electrochemical properties of Ni(OH) 2 /CNTs prepared by electrochemical deposition were investigated in this article. The results show that deposits of Ni(OH) 2 has high purity and can optimize the electronic and ionic conductivity to minimize the total resistance of the system and maximize the performance characteristics as supercapacitor electrodes. The specific capacitance at a scan rate of 2 mV/s reaches as high as 2486 F/g, which gives the composites potential application as high-performance supercapacitor electrode materials. Meanwhile, the products were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), and transmission electron microscopy (TEM).
