Аннотация: The graphitization of diamond particles in the copper-diamond composite materials used for low voltage electro-contacts was investigated by SEM, TEM and X-ray diffraction (XRD) analyses. The results show that although diamond is a metastable allotropic modification of carbon, the diamond particles are not graphitized to an apparentПоказать полностьюextent after sintering at 1150-1220 K in the copper-diamond composite. The reason for this phenomenon was discussed. The diamond powders prepared by explosion synthetic method are supposed to possess higher resistance to graphitization and thus benefit the performance of the copper-diamond composite used for electro-contacts.
