【期刊论文】New method of carbon onion growth by radio-frequency plasma-enhanced chemical vapor deposition

Large quantities of carbon onions with high purity were synthesized by radio-frequency plasma-enhanced chemical vapor deposition. The produced carbon onions are solid, clean and can be separated easily from the catalytic particles. The formation of onions is based on the formation of many cages in successive stages from the core to the surface. Around the edge of a carbon onion, discontinuous curved lines are shown in the high-resolution TEM image, reflecting the wavy behavior of carbon onions.

【期刊论文】Preparation, morphology and microstructure of segmented graphite nanofibers

Vapor-grown of segmented graphite nanofibers were prepared by pyrolysis of acetylene at 600 800C using a foam Ni catalyst. Through transmission electron microscopy observation, it was found that this kind of nanofiber looks like a line of lens-like segments with nearly equal separation, which consist of well-ordered graphite platelets intermittently stacked perpendicularly to the filament axis. It was suggested that the catalyst particles adopting a thin slice shape and the flow rate of acetylene are critical for forming segmented graphite nanofibers. The formation mechanism of segmented graphite nanofibers has also been discussed.

【期刊论文】Electrodeposited nickel composites containing carbon nanotubes

Nickel composites containing carbon nanotubes were prepared by codepositing carbon nanotubes uspended in an electrolyte with growing nickel during electrodeposition. There is a saturation concentration for dispersing carbon nanotubes completely in the solution. Carbon nanotubes codeposition was found to reach a maximum and then decrease with carbon nanotubes concentration in the solution, current density and agitation rate. The microstructure of the coatings have been examined by electron microscopy.

【期刊论文】Corrosion behavior of carbon nanotubes-Ni composite coating

Ni-carbon nanotube (CNTs) composite coatings were deposited on a carbon steel by electrodeposition. The effect of incorporation of CNTs into the nickel coating on the morphology of the coating surface and corrosion properties was investigated. Scanning electron microscopy (SEM) showed that the CNTs appear well dispersed in the nickel layer. Corrosion tests were performed in aqueous NaCl (3.5wt.%) using a weight loss method and electrochemical measurements for bare, pure nickel coated and CNTs-nickel coated samples. The results showed that addition of CNTs in the deposition process of nickel significantly increased the resistance to corrosion. The anti-corrosion mechanism of the composite coating is also discussed.

【期刊论文】Dry friction and wear characteristics of nickel/carbon nanotube electroless composite deposits

Ni/carbon nanotube (Ni/CNTs) composite coatings were deposited on carbon steel plate by electroless deposition. The friction and wear properties were examined under dry sliding conditions using the ball-on-disk configuration. For reference, carbon steel plate was coated with Ni, Ni/SiC and Ni/graphite. The results show that the Ni/CNT coating has a microhardness value of 865Hv, greater than for SiC reinforced composite deposits. The Ni/CNTs composite coating possesses not only a higher wear resistance but also a lower friction coefficient, resulting from their improved mechanical characteristics and the unique topological structure of the hollow nanotubes.

Multi-walled carbon nanotubes (MWNTs) were treated with mixture of sulfuric acid and nitric acid. The surface modification of the oxidized MWNTs was achieved by refluxing the MWNTs with stearic acid (SA). The modified MWNTs were examined by the transmission electron microscope, scanning electron microscope, Raman spectroscopy and Infrared spectroscopy. Furthermore, the modified MWNTs were added to base lubricant and the tribological properties of resultant MWNTs lubricant were investigated by using a pin-on-plate wear tester. The results indicated that an esterification was formed in the oxidized MWNTs and SA, and the modification led to an improvement in the dispersion of MWNTs and the tribological properties of MWNTs as lubricant additive.

The array of aligned, isolated carbon nanotubes was achieved by using chemical vapor deposition catalyzed by round alloy particles on the Agfilm. The round alloy particles were prepared by annealing FeNi islands on the Ag film deposited by magnetic sputtering on the silica substrate. The size of the round particles was controlled by the size of the FeNi islands films and the heat treated temperature. The array of carbon nanotubes on the Ag film was obtained at 7008C when the round alloy particles was about 30
