| 摘 要： | 本文分别研究了微米TiC和微米TiN对陶瓷刀具材料Al2O3-3Y-ZrO2微观结构和力学性能的影响。结果表明,添加微米TiC后,陶瓷刀具材料的断裂韧度略有下降。添加微米TiN的陶瓷刀具材料A5Nm20Z在烧结温度为1650℃、烧结压力为30MPa和保温时间为30min时的力学性能最好,抗弯强度、断裂韧度和维氏硬度分别为845.14MPa、4.87MPa·m1/2和16.40GPa。

| Abstract: | The effect of micro-scale TiC and micro-scale TiN on microstructure and mechanical properties of ceramic tool materials Al2O3-3Y-ZrO2 were investigated systematically. The fracture toughness of A5Tm20Z(Al2O3-3Y-ZrO2-TiCm)fabricated by adding micron-scale TiC into Al2O3-3Y-ZrO2 composite materials decreases. Ceramic tool materials A5Nm20Z fabricated by adding micron-scale TiN 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 sintering pressure of 30MPa, and its flexural strength, fracture toughness and Vickers hardness are 845.14MPa、4.87MPa·m1/2和16.40GPa respectively. |
