摘要：

Multi-walled carbon nanotubes (MWCNTs) were coated with a nanometer sized SiC layer by the reaction of SiO(g) and CO(g). The onset temperature of oxidation increased from 560 to 700degreesC with the SiC coating. Composites made from SiC-coated MWCNTs dispersed in WC-10 wt.%Co were successfully sintered at the low temperature of 1050degreesC using the pulsed electric current sintering. The microhardness of these composites was 20 GPa, which is 2.5 GPa (14%) higher than that of WC-10 wt.%Co. (C) 2004 Published by Elsevier B.V.
