Effect of TaC on Phase, Microstructure and Mechanical Properties of Ti(C_0.7N_0.3)-Based Cermets

School of Electromechanical Engineering, Guangdong University of Technology, Guangzhou 510006, China

摘要

摘要: 为了制备高硬度高韧性的Ti(C_0.7N_0.3)基金属陶瓷，采用了1600℃真空无压烧结制备了含TaC的Ti(C_0.7N_0.3)-WC-Mo₂C-VC-AlN-Ni/Co系金属陶瓷，研究了TaC (0wt%、5wt%、10wt%、15wt%)对金属陶瓷的物相、显微结构、力学性能的影响。结果表明，随着TaC含量增加，Ti(C_0.7N_0.3) (200)主峰逐渐向低角度偏移，环形相的厚度逐渐增大，金属陶瓷的维氏硬度和断裂韧性均先增大后减小。当TaC含量为10wt%时，核芯相细化，尺寸离散度最小，环形相发育更完整且均匀，金属陶瓷获得最高的维氏硬度和断裂韧性，分别为17.79 ± 0.15 GPa和10.20 ± 0.39 MPa·m^1/2。

Abstract: In order to prepare Ti(C_0.7N_0.3)-based cermets with high hardness and high toughness, Ti(C_0.7N_0.3)-WC-Mo₂C-VC-AlN-Ni/Co cermets containing TaC were prepared by vacuum pressureless sintering at 1600℃. The effects of TaC (0wt%, 5wt%, 10wt%, 15wt%) on the phase, microstructure and mechanical properties of cermets were investigated. The results show that with the increase of TaC content, the main peak of Ti(C_0.7N_0.3) (200) gradually shifts to a lower angle, the thickness of rim phase increase gradually and the Vickers hardness and fracture toughness of cermet firstly increased and then decreased. When 10wt% TaC is added, the core phase size of cermets is refined with the smallest, and the rim phase is more complete and uniform, leading to the maximum Vickers hardness (17.79 ± 0.15 GPa) and fracture toughness (10.20 ± 0.39 MPa·m^1/2) of cermet.
