In order to study variation of the thermal conductivity of the diamond/Cu composite prepared by high pressure infiltration at low temperature zone,the diamond/Cu composites with different diamond particle sizes(100μm,250μm and 400μm)were separately prepared by high pressure infiltration(HPF)method,the scanning calorimetry was used to analyze and evaluate the thermal conductivity of the diamond/Cu composites at low temperature,and SEM was used to analyze the microstructure of the composites.The results show ...
