Get A QuoteHigh-energyball millingis successfully used to produce magnesium matrix nanocomposites reinforced with SiC nanoparticles. Changes in morphology and microstructural features of the milled powders were characterized in order to highlight advantages of the mechanicalmillingprocess and evaluate the role of the SiC nanoparticles.
Get A QuoteA wetball millingroute was used to synthesiseSiC-graphenecore-shell nanoparticles in situ from graphite andSiCnanoparticles. Graphite flakes were gradually exfoliated into fresh graphene nanosheets (GNSs) without significant defects, which is attributed to mechanical shearing and moderate impaction forces between graphite flakes,milling ballsandSiCnanoparticles during the wet milling.
