| Abstract: | Carbon nanotubes(CNTs)were coated by tungsten layer using carbonyl thermal decomposition process and tungsten hexacarbonyl as a precursor.Aluminum matrix composites reinforced with W-coated CNTs(W-CNTs)were fabricated by mechanical milling and spark plasma sintering processes.The influences of milling time and W-CNTs content on the mechanical properties and electrical conductivity of composites were studied.The results show that the relative density of the composites fabricated by 6 hours' milling and spark... |
