A deposit of carbon nanoparticles based on an onion-like structure was fabricated from detonation nanodiamond powders by a novel plasma spraying process, electromagnetically accelerated plasma spraying (EMAPS). EMAPS was able to transform nanodiamonds to onion-like structured carbon within 300 mus through a thermal graphitization process in which the temperature of the particles would be in the range of 2700-4500 K. Synthesized onion-like carbon nanoparticles were spherical or polyhedral. The G-band in the UV-Raman spectra of the produced deposits was found to be a superposition of a characteristic band of well-formed carbon onions at 1571 cm(-1) and the G-band of defective carbon onions at 1592 cm(-1). The availability of a plasma spraying process for developing solid lubricant coatings incorporating nanodiamond and onion-like carbon was demonstrated. (C) 2003 Elsevier Ltd. All rights reserved.
