添加剂TiO_2和Cr_2O_3对复合陶瓷Mullite/ZrO_2/Al_2O_3的影响

Effect of TiO_2 or Cr_2O_3 Additives on Mullite/ZrO_2/Al_2O_3 Composite Ceramics

利用添加剂改善结构陶瓷材料的性能是一种较佳的方法,复合陶瓷mullite/ZrO_2/Al_2O_3具有较高的力学性能。试验证明:加入不同的添加剂对复合陶瓷有不同的影响,TiO_2会使材料的力学性能大幅度降低;Cr_2O_3会使材料的硬度显著提高。

It is a good way to improve the properties of the structural ceramics by using additives. The mullite/ ZrO2/Al2O3 composite ceramics have good mechanical property.The experimental results have shown that adding different additives would effect some properties of composite ceramics: the mechanical property would be sharply decreased by adding TiO2, and the hardness would be greatly increased by adding Cr2O3.
