Ti(c,N)基金属陶瓷是由粘结相粉末、硬质相粉末和添加剂粉末通过粉末冶金的方法而制备的。各组无粉末的加入量,决定了材料的最终成分,进而影响材料的组织和性能[1,2]。本文主要介绍添加剂碳粉量对 Ti(c.N)基金属陶瓷组织性能的影响。碳粉的加入量受原料粉末中氧和 MO 粉添加量的影响。碳粉的加入量,一方面要确保形成 MO_2C 和脱氧所需的碳量,使烧结后的组织处于两相区内;另一方面还要使金属陶瓷中的
Ti (c, N) -based cermets are prepared by powder metallurgy from binder phase powders, hard phase powders and additive powders. The powder-free addition of each group determines the final composition of the material, which in turn affects the microstructure and properties of the material [1,2]. This article describes the additive amount of carbon powder on the microstructure and properties of Ti (c.N) -based cermets. The amount of toner added is affected by the amount of oxygen and MO added in the raw material powder. The amount of toner added, on the one hand to ensure the formation of MO_2C and deoxidation required amount of carbon so that the sintered tissue in the two-phase region; the other hand, but also to make the cermet
