加入TaC对Ti3SiC2陶瓷材料性能的影响
Effect of Addition of TaC on Properties of Ti3 SiC2 Ceramics
摘要
Abstract
The material of 20% (mass fraction, same below ) TaC/Ti3 SiC2 was prepared by reactive hot pressing method. The phase constituent, mechanical properties and oxidation resistance were investigated. The results showed that;(l) The densification, flexural strength and fracture toughness of 20% TaC/Ti3SiC2 increase with the increase of hot pressing temperature; (2) The oxidation resistance of 20% TaC/Ti3SiC2 is much higher than that of monolithic Ti3SiC2 and 20% SiC/Ti3SiC2 composites; (3) The oxidized layers of TaC/ Ti3SiC2 are composed of two layers. The outer layer is TiO2. And the inner layer is the mixture of TiO2 , SiO2 and the eutectoid of TiO2 and Ta2O5.关键词
