| Abstract: | The Cu/diamond composites containing 90% (volume fraction) diamond particles were prepared at 1200°C under a pressure of 5 GPa by high pressure liquid infiltration method, giving a measured thermal conductivity of 662 Wm-1K-1. The characterization of composites by means of SEM, EDS and XRD shows that the interfacial bonding of Cu/diamond is strong, and a transition layer exists between diamond and Cu. Besides, some diamond particles are found to be inter-connected. The Cu/diamond composites fabricated by this method exhibited a thermal conductivity far superior to those produced by other means. |
