The preparation of carbon nanotube (CNT)/copper composites and the effect of the number of CNT walls on their hardness, friction and wear properties. Guiderdoni, C., Pavlenko, E., Turq, V., Weibel, A., Puech, P., Estournes, C., Peigney, A., Bacsa, W., & Laurent, C. Carbon, 58:185–197, July, 2013. WOS:000318835000019

Carbon nanotubes with 2, 3, 8 and 20 walls are mixed with a copper powder (micrometer sized) and consolidated by spark plasma sintering. The microhardness of resulting composites is found to be over 50% higher than that for Cu and the friction coefficient against a steel ball is decreased by a factor of 3-4 while the wear and wear rate are reduced by a factor of 10-20. Raman maps of selected specimens outside and inside the worn surface show that double-wall carbon nanotubes remain intact. The reasons for the effect of the number of walls and carbon content are discussed. (C) 2013 Elsevier Ltd. All rights reserved.
