Graphite is a very attractive candidate for copper-metal matrix composites. However, copper does not wet graphite, which makes the production of copper-graphite composites difficult. Because of the strong possibilities of these combinations in forming highly desirable composites, copper-carbon composites prepared by hot uniaxial pressure were investigated. The copper-carbon interface is of the samples was examined microscopically using optical microscopy. The observed microstructure at copper interface is composed of copper-carbon interaction layer. The adhesion between copper and graphite was achieved. However, there is no intimate contact between copper and graphite film at interface. To determine the diffusion of carbon through copper matrix by X-ray diffraction was used.
