以钛铁矿为原料,采用分步球磨后碳热还原法,进行Ti(C,N)复合粉末的制备,并对Ti(C,N)复合粉末的粒径、形貌、物相组成和烧结性能进行测试与分析。结果表明:Ti(C,N)复合粉末粒径为2~5μm,呈正态分布,由Ti(C,N)和α-Fe组成。试验制备Ti(C,N)复合粉末烧结体的抗弯强度达到商业Ti(C,N)粉末烧结体的98%、断裂韧性达到商业Ti(C,N)粉末烧结体的110%。 The Ti (C, N) composite powder was prepared by ilmenite as raw material and the carbothermal reduction method was used. The size, morphology, phase composition of Ti (C, N) Sintering performance for testing and analysis. The results show that the particle size of Ti (C, N) composite powder is 2 ~ 5μm with normal distribution and composed of Ti (C, N) and α-Fe. The flexural strength of the as-prepared Ti (C, N) composite powder sinter reached 98% of the commercial Ti (C, N) powder sinter and the fracture toughness reached 110% of the commercial Ti (C, N) powder sinter.
