【Abstract】 The microstructure and properties of copper-graphite and Cu/Copper-coated graphite composites have been compared to those prepared by powder metallurgy.The results show that in Cu/Copper-coated graphite composite,the volume density and the electrical conductivity decreased with the increasing of copper-copper-coated graphite,while the graphite in it is fairly well-distributed and the copper helps to form the three dimensional net-shape,thus making the composite have better electrical conductivity than the copper-graphite composite.更多还原
