摘要
采用微波加热方法在人造金刚石表面镀铬,并采用微波加热烧结制备高导热金刚石/铜复合材料。探讨了金刚石表面镀铬对金刚石与铜之间浸润性的影响。探讨了微波烧结金刚石/铜复合材料在不同生坯压力和不同金刚石体积分数下的致密度。结果表明,微波烧结过程中金刚石与铜基体能够实现较为紧密的结合。随着金刚石体积分数的增加,致密度逐渐减少。随着生坯压力的增加,金刚石/铜复合材料的致密度逐渐增加。分析了微波强化烧结对金刚石/铜复合材料致密度的影响。
Cr3 C2 coatings were formed on diamond particles for improving the wettability between diamond particles and copper. Copper.diamond composites with Cr3C2 coatings on diamond particles have been fabricated by microwave sintering method. The microstructure of interfacial bonding between diamond and copper was discussed. The microstructures of these composites show uniform diamond particle distribution in the copper matrix. The effect of diamond volume fraction and compacting pressure on the density of diamond/copper was investigated. The theory of the microwave sintering of diamond / copper composite material was discussed.
