摘要

为了改善ZrO

陶瓷材料的综合力学性能

探讨了添加不同粒径和含量的Al

粉末对ZrO

-TiB

-Al

纳米复合陶瓷材料微观结构和力学性能的影响.采用真空热压烧结工艺制备了ZrO

纳米复合陶瓷材料

烧结温度为1 450 ℃

热压压力为30 MPa

保温1 h.结果表明:微米Al

粉末的体积分数为10%时

ZrO

-TiB

-Al

纳米复合陶瓷材料的抗弯强度最高

可达743 MPa; 添加纳米Al

粉末对材料的韧性提高明显

最高可达11.37 MPa·m

1/2

但不同粒径的Al

粉末对材料的硬度影响则不明显

材料的硬度随Al

含量的增加而增加.

Abstract

To improve the comprehensive mechanical properties of ZrO

ceramic die material

the effects of different particle size and content of Al

powders on the microstructure and mechanical properties of ZrO

-TiB

-Al

nanocomposite ceramic die materials were investigated. ZrO

nanocomposite ceramic die material was prepared with vacuum hot pressing technique at 1 450 ℃ for 1 h. under 30 MPa. The results show that the

highest flexural strength of ZrO

-TiB

-Al

nanocomposite ceramic die material reaches 743.49 MPa with 10%(volume fraction)Al

micrometer sized powders. The fracture toughness increased obviously along with the increase of Al

nanometer sized powders

and reached 11.37 MPa·m

1/2

. Vickers hardness did not change obviously with different Al

powders

while it greatly increased with the increases of Al

content.
