| Abstract: | The relation of the thermal conductivity of diamond/Ag composites to the particle size and volume fraction of particles in the composites is investigated in this paper.The influence of thermal boundary resistance on thermal conductivity of composite material is discussed in particular.The thermal conductivity of diamond/Ag composites can be improved by the titanizing diamond particles,because of the improved wettability between diamond and silver,and reduction of thermal boundary resistance. |
