Proper process and parameter were investigated to coat Cu or Ni on graphite fl ake (G f ) by electroless plating. Microstructuralcharacterization indicated that the Cu/Ni was coated on the G f uniformly and comprehensively. Then aluminum matrixcomposites reinforced with Si and graphite were fabricated by a unique vacuum gas pressure infi ltration. The thermal conductivityand mechanical properties of the composites, both with and without Cu or Ni coating layers on the graphite surface,have been studied. The obtained results indicated that the mechanical property of the Cu or Ni coated G f /Si/Al compositesdramatically increased, as compared with the non-coated G f /Si/Al composite. In the meantime, Cu or Ni coated G f provedto have better wettability and interfacial bonding with the aluminum matrix, which were expected to be a highly sustainableand dispersible reinforcement for metal matrix composites.
