低成本金刚石/铝复合材料的研究

Research on the Low-cost Diamond/Aluminium Composites

采用无压浸渗工艺制备出低成本金刚石/铝复合材料,并对复合材料的显微组织、界面及导热性能进行了研究。实验结果表明,采用无压浸渗工艺制备的金刚石/铝复合材料,组织致密,颗粒分布均匀。金刚石/铝复合材料的热导率随着金刚石含量的增加而增加,热导率最高可达298W/(m·K)。

The low-cost diamond/alumimum composites were prepared by the pressureless metal mtiltrauon process, and the mierostructure, inter{ace and thermal properties were investigated. The results indicate that the dia- mond/aluminium composites have high relative density, and the diamond particles distribute uniformly. With the dia- mond volume fractions increasing, the thermal conductivity o{ diamond/aluminium composites increase, and the ther- mal conductivity of these diamond/aluminium composites is as high as 298 W/（m· K）.
