MgAl_(2)O_(4)掺杂对ZTA-MgAl_(2)O_(4)复相陶瓷力学及热学性能影响

摘要

MgAl_(2)O_(4) is a very suitable reinforcing phase owing to the advantageous performance such as high melting point,high strength,high hardness,corrosion resistance and good thermal shock stability.In this paper,the effects of MgAl_(2)O_(4) addition on microstructure and mechanical properties of ZTA-MgAl_(2)O_(4) composite ceramics prepared by Spark Plasma Sintering(SPS)were investigated.
