A study of cast alloys with partially dispersed graphite Wear Behavior of Graphite Dispersed Al Sn Si Alloys
A study of cast alloys with partially dispersed graphite was carried out to improve the mechanical properties as well as to retain excellent wear resistanceAlthough the graphite particles added up to 8mass do not improved the friction coefficient of as cast alloys at the lower applied load an applied load for the Al Sn Si alloy with 5 8wt of graphite additions reaches 060MPa whereas that for the non added base alloy is only 045MPa

Structural optimization of graphite for high performance Graphite/polymer based composite bipolar plates 3
To investigate the effects of dispersion and packing density the large graphite particles were decorated with fluorinated ethylene propylene powders by ball milling and the master batch of well dispersed small graphite particles and polymer master batch was mixed with large graphite particlThe conductive network built up by the binary filler system is assumed to consist of highly dispersed carbon black particles bridged by graphite particl For fuel cell application through plane conductivities of at least 500 S/cm are necessary
