研究了影响铜—石墨材料密度的工艺因素。研究结果表明， 石墨粉的形状和粒度对材料密度的影响不可忽略， 细粒度的天然鳞片状石墨粉有利于提高压坯密度。复压工艺对提高材料最终密度效果显著。烧结温度和初压压力对密度的影响不是主要的。对试样进行性能测试的结果说明， 密度高的试样， 其各项物理性能均优于密度低的试样 The factors affecting the density of copper-graphite material were studied. The results show that the shape and size of graphite powder can not neglect the density of the material. The fine-grained natural flaky graphite powder is helpful to improve the density of green compact. Replenishing process to improve the final density of materials significant effect. The effect of sintering temperature and initial pressure on density is not significant. The results of the performance test on the samples show that the samples with high density have better physical properties than those with low density
