  • Preparation Of Graphite Dispersed Copper Composite

    The graphite particles were placed between the two cop-per plates, as shown in Fig. 2. The layer of graphite particles sandwiched between two copper plates was approximately 0.8~1 mm in height. The sample was ˚xed by a wooden clip so that the graphite particles did not fall down during weld-ing.
