The interfacial phenomena in thermally sprayed (plasma and high-velocity oxyfuel spraying) hypereutectic Al-Si composite with multiwalled carbon nanotube (MWCNT) reinforcement have been analyzed both theoretically and experimentally. The formation of an ultrathin beta-SiC reaction layer at the interface is confirmed. Plasma sprayed composite exhibits a thicker SiC layer (similar to 5 nm) than the high-velocity oxyfuel sprayed composite (similar to 2 nm). The presence of SiC layer formation is also corroborated in a chemical vapor deposition experiment where Si was deposited on MWCNTs. The formation of beta-SiC is responsible for the improved wettability of the molten Al-Si alloy matrix with MWCNT reinforcement. (C) 2006 Acta Materialia, Inc. Published by Elsevier Ltd.
