Effect of ball

nbsp 0183 32 It is indicated that the GNSs are gradually dispersed into the copper matrix with increasing the ball-milling time and a uniform dispersion is achieved after ball-milling for 5 h When the content of GNSs in the composite is 0 5 wt GNSs distribute randomly in the composite and the interface bonding is good which is benefit to enhance the mechanical properties of composite...

In Situ synthesis of SiC

nbsp 0183 32 A wet ball milling route was used to synthesise SiC-graphene core-shell nanoparticles in situ from graphite and SiC nanoparticles 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 balls and SiC nanoparticles during the wet milling...
