摘要
用ＣＶＤ法合成了金刚石－铜的复合材料。实验证明，合成金刚石－铜复合材料相对厚度的合适范围ｈ／Ｈ＝５～７。复合材料的热传导系数随合成温度Ｔ０的增高而增大。在Ｔ０＝１２４３Ｋ时α≤７００Ｗ·Ｍ－１·Ｋ－１。
The diamond film on copper substrates is obtained by CVD method.The experiments have showed that the relative thickness h/H =57,at which the diamond-copper composite material is joined,is apposite.The thermal conductivity of the composite materials increases when the temperature T0 rises.At the temperature T0 =1243K,the thermal conductivity 700Wm-1K-1 nearly equals to that of artificial diamond produced under high pressure.
