“…This method has been widely used to produce a massive amount of CNT [16][17][18][19] or carbon onions [20][21][22]. Usually beside carbon onions, CNCs were obtained [20][21][22] or CNTs [23].…”

“…CNTs can be used for nanochannels, hydrogen storage and electron transport materials because of their tubular structure and convenient adjustability of conductivity [3,[13][14][15]. The high surface-to-volume ratio and sharp edge of CNSs are attractive for field electron emission, fuel cells, high performance capacitors and micro-and nano-electronic technologies [6,[16][17][18][19][20].…”

“…However, processing of these composites particularly metal/CNT composites has been rather challenging [8]. Of important challenges to note are the following: (1) segregation and distribution of CNTs within the metal matrix, (2) structural degradation of CNTs at elevated processing temperatures, (3) reaction between carbon and the molten metal, and (4) poor wetting between CNTs and metal matrix.…”

In this study, the effect of incorporation of carbon nanotubes into pure copper was investigated through friction stir processing (FSP). To this end, FSP has been performed using one and three passes. Moreover, the changes in peak temperature of one-pass friction stir processing performed by tools with different shoulder diameters have been recorded. It was found that for the tool with smaller shoulder, the process temperature peak has been significantly reduced. Remarkable reduction in grain size of Cu/carbon-nanotube nanocomposites was observed as compared with the pure copper. Raman spectroscopy results proved a higher extent of degradation of carbon nanotubes upon increasing the friction stir processing passes. On the other hand, microhardness and wear results showed that as the carbon nanotubes are introduced to the pure copper, hardness of composites processed via one-and three-friction stir processing passes showed enhancements of 65 and 105 %, respectively, and the weight losses were also decreased 31 and 68 %, respectively. It was also observed that friction coefficient of one-pass processed composite is lower than that of the pure copper due to the presence of carbon nanotube clusters. Whereas, the friction coefficient of three-pass processed composite was increased regarding to the pure copper. The reduction in slope of wear weight loss upon increasing the applied force at the wear test signified the higher efficiency of the processed composites under harsh conditions.
