中文摘要: 采用热压烧结工艺制备了AlN-TiC复相陶瓷。通过XRD、SEM和激光导热仪研究了TiC含量和烧结温度对复相陶瓷导热性能的影响，并对A1N-TiC的相组成和显微结构进行了观察分析。结果表明，随着TiC质量分数增至50%时，热导率由102.9 W/(m?K)下降到46.6 W/(m?K)；在TiC含量为10%时，随着温度的升高，热导率从59.8 W/(m?K)增加到83.6 W/(m?K)。
Abstract:AlN-TiC composite ceramics were prepared by hot pressed method. The effects of TiC content and temperature on thermal conductivity of composite ceramics were investigated by XRD、SEM and laser thermal conductivity apparatus. The phase composition and microstructure were studied. The results show that thermal conductivity weakens gradually from 102.9 W/(m?K) to 46.6 W/(m?K) with increase of TiC content of mass fraction to 50%. When TiC mass fraction is 10%, thermal conductivity strengthens from 59.8 W/(m?K) to 83.6 W/(m?K) gradually with increase of temperature.
