| 摘 要： | 文章研究了粘结剂的含量、成型压力和烧结工艺对SiCp预制坯性能的影响规律,结果表明:随着粘结剂含量的增加,预制坯中SiC颗粒的体积分数越来越小,抗压强度在粘结剂含量为30%时达到最大,随后缓慢下降;成形压力在10-25MPa之间时,随着成型压力的增大,预制坯中SiC颗粒的体积分数越来越大,其抗压强度也越来越大;在800℃以下烧结时,随着烧结温度的提高,预制坯中SiC颗粒的体积分数变得越来越小,但在800℃以后没有明显的变化,预制坯的抗压强度随着烧结温度的提高而增大,在1100℃时,效果最好。

| Abstract: | The effects of binder content,forming pressure and sintering processes on the particle volume fraction and strength of the preforms were investigated.The results show that the particle volume fraction of the preforms decreases while the strength of preforms increases with the increase of binder content,and the compressive strength of preforms comes up to a maximum value when the content of binder is 30%,then decreases slowly.The particle volume fraction and the compressive strength of preforms increase with... |
