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...

A study on the electrocodeposition processes and properties of Ni–SiC nanocomposite coatings

2010

Ni-SiC nanocomposite coatings were prepared on a brass substrate by electrocodeposition. The electrodeposition was carried out by adding the SiC nanoparticles to a nickel-containing bath. Nickel deposition processes were analyzed by cathodic polarization curves, and the plating parameters were determined preliminarily by analyzing the effects of different technological parameters on the deposition process. Then, electrocodeposition processes were carried out with different concentrations of SiC nanoparticles in the bath. The effects of current density, stirring rate, and SiC nanoparticle's concentration in the plating bath on the hardness of coatings were investigated by microhardness tests. Besides the microhardness tests, wearing tests and corrosion tests were also applied to the coatings with the highest hardness and coatings of pure nickel. The structures and surface morphologies of the coatings were examined by X-ray diffraction (XRD) and scanning electron microscopy (SEM) methods. The experimental results show that the microhardness of the codeposited coating increases with increasing current density and attains a maximum at the SiC concentration of 6 g/L. The decrease in the microhardness at higher SiC concentrations may be due to agglomeration of nanosized particles in the plating bath. Increasing the stirring speed did not give a better quality deposition as coatings produced at low stirring rates always had higher microhardness values than did those at high stirring rates. Furthermore, the Ni-SiC nanocomposite coatings have lower friction coefficient and better corrosion resistance than those of pure nickel coatings.

Electrodeposition of tertiary Alumina/Yitria/carbon nanotube (Al 2 O 3 /Y 2 O 3 /CNT) nanocomposite by using pulsed current has been studied. Coating process has been performed in nickel sulphate bath and nanostructure of the obtained compound layer was examined with high precision figure analysis of SEM nanographs. The effects of process variables, i.e. Y 2 O 3 concentration, treatment time, current density and temperature of electrolyte have been experimentally studied. Statistical methods were used to achieve the minimum wear rate and average size of nanoparticles. Finally the contribution percentage of different effective factors was revealed and confirmation run showed the validity of the obtained results. Also it has been revealed that by changing the size of nanoparticles, wear properties of coatings will change significantly. Atomic force microscopy (AFM) and transmission electron microscope (TEM) analysis have confirmed smooth surface and average size of nanoparticles in the optimal coating. Key words: yitria, electrodeposition, tertiary nanocomposite coatings, wear, carbon nanotube.Nickel and nickel-based alloys are used widely for numerous applications, which most of them require corrosion, wear and heat resistances, including different turbine plants, nuclear power systems, and chemical and oil industries.Ceramic or metal matrix nanocomposite coatings usually have special properties such as dispersion hardening, self-lubricity, high temperature inertness, good wear and corrosion resistance, chemical and biological compatibility [1][2][3][4][5][6][7]. This accounts for the increased application of Ni-based nanocomposites in different industries. In order to meet the requirement for developing novel metal-based nanocomposites, many preparation techniques have been investigated. Considering a technique conducted at a normal pressure and ambient temperature and with low cost and high deposition rate, electrodeposition is considered to be one of the most important techniques for producing nanocomposites and nanocrystals [8][9][10][11].In this paper, tertiary nanocomposite coatings consisting of nanometric-sized Al 2 O 3 /Y 2 O 3 /CNT particles embedded in a Ni-matrix by pulsed electrodeposition method were studied. The nanostructure and wear resistance of obtained nanocomposites were investigated with respect to the different effective factors of coating process. Ni matrix composite coatings containing nano-sized Al 2 O 3 /Y 2 O 3 /CNT fine particles with different average sizes of nanoparticles were prepared in a nickel sulphate bath. The wear performance of these coatings and its relation to the distribution of nanopaticles has been analyzed in a systematical way.The design of experiment (Taguchi method) [12][13] took into account the influencing extent of individual process parameter. This consideration led to the selection of four influential factors, i.e. Y 2 O 3 concentration, time, current density and
