摘　　要：人造金刚石由于其自身高的热导率、低的热膨胀系数和相对低的价格已成为制造新型散热材料的研究热点。本文主要介绍了近年来在金刚石/铝和金刚石/铜复合散热材料的致密度、合成方法、热导率、界面等方面的一些研究进展。添加活碳元素(硼、铬等)和在高压下使金刚石直接成键可能是提高金刚石/金属散热材料热导率的两种有效途径。Synthetic diamond is competitive in heat dispersing materials, because it has high thermal conductivity, low coefficient of thermal expansion and lower price. This paper overviews the manufacturing process, compact density, thermal conductivity and the interfaces of the diamond/aluminum and diamond/copper composites. There may be two ways of improving the thermal conductivity of diamond/metal composites, one is direct bonding between diamonds in high pressure, the other is adding active carbon elements （B, Cr, etc）.
