摘要
本文采用热压工艺制备ＴｉＣ和Ａｌ_２Ｏ_３共同补强Ｙ－ＴＺＰ基复相陶瓷，研究了复相陶瓷的相组成、力学性能及显微结构．发现复相陶瓷的高温强度得到显著提高，１０００℃时，组成为３０ｖｏｌ％ＴｉＣ－（２５ｖｏｌ％Ａｌ２Ｏ３／１．８Ｙ－ＴＺＰ）复相陶瓷抗弯强度高达６１４ＭＰａ．ＴｉＣ颗粒补强机制在高温下发挥了重要作用．
Y-TZP (yttria-stabilized tetragonal zirconia) matrix composites reinforced by TiC and Al_2O_3 particles were fabricated by hot-pressing. Mechanical properties, microstructure and phase composition of the composites were investigated. High temperature strength of Y-TZP was significantly improved by the addition of both Al_2O_3 and TiC particles. The strength of 30vol% TiC/(25vol%Al_2O_3 /1.8Y-TZP)composition at 1000℃, reaches a high value of 614MPa. This is mainly attributed to the strengthening effect caused by TiC particles at high temperatures.
