摘　　要：研究了AlN添加量(0,1%,2%,3%,质量分数)对Ti(C,N)基金属陶瓷硬度、抗弯强度以及抗氧化性能的影响。结果表明:不同AlN添加量下的金属陶瓷主要由Ti(C,N)、Ni3Al和镍相组成;随着AlN添加量增加,金属陶瓷的硬度增大,抗弯强度先增大后减小,AlN添加量为2%时达到峰值;与未添加AlN相比,添加2%AlN金属陶瓷的氧化质量增加较慢,氧化膜结构更致密,抗氧化性能更好。The effect of AlN addition amount(0,1%,2%,3%,mass fraction)on the hardness,bending strength and oxidation resistance of Ti(C,N)-based cermets was studied.The results show that the cermets with different addition amount of AlN were all mainly composed of Ti(C,N),Ni3Al and nickel phases.With increasing the addition amount of AlN,the hardness of the cermet increased,and the bending strength increased first and then decreased,reaching the peak value with 2%AlN.The oxidation mass gain of the cermet with 2%AlN increased slowly compared with the without AlN,and the oxide film structure was relatively dense,indicating the better oxidation resistance.
