| Abstract: | The effect of nano-scale TiC on mierostructure and mechanical properties of nano-seale zireonia toughening alumina matrix ceramic tool materials were investigated systematically. Ceramic tool materials A5Tn20Z （Al2O3 - 3Y- ZrO2 - TiCn） fabri- cated by adding nano-scale TiC into Al2O3 - 3Y - ZrO2 composite materials have optimal mechanical properties when its fabrication technology is a fabrication temperature of 1650℃,, a duration time of 30min and a fabrication pressure of 30MPa, and its flexural strength, fracture toughness and Viekers hardness are 904.7MPa, 4. 16MPa·m1/2, 17.43GPa respectively. |
