High-entropy carbide reinforced TiCN-based metal ceramic with high hardness and high toughness as well as preparation method and application of high-entropy carbide reinforced TiCN-based metal ceramic
The invention belongs to the field of metal ceramic cutting and processing, and discloses a high-entropy carbide reinforced TiCN-based metal ceramic with high hardness and high toughness and a preparation method and application of the high-entropy carbide reinforced TiCN-based metal ceramic. The metal ceramic is prepared by the following steps: carrying out ball milling on TiC0. 7N0. 3, WC, Ni, Co, Mo2C, VC, AlN and (Ta0. 2W0. 2V0. 2Mo0. 2Nb0. 2) C high-entropy carbide powder together to obtain mixed powder, drying, carrying out dry pressing and cold isostatic pressing molding, fully wrapping a green body with carbon powder, sintering at 1450-1600 DEG C, and carrying out heat preservation. The (Ta0. 2W0. 2V0. 2Mo0. 2Nb0. 2) C high-entropy carbide powder is prepared by the following steps: mixing and ball-milling six kinds of powder, namely Ta2O5, V2O5, WO3, Nb2O5, MoO3 and C, drying, and carrying out a carbothermal reduction method at the temperature of 1,600-1,700 DEG C.
本发明属于金属陶瓷切削加工领域，公开了一种具有高硬度和高韧性的高熵碳化物增强TiCN基金属陶瓷及其制备方法和应用。所述金属陶瓷是将TiC0.7N0.3、WC、Ni、Co、Mo2C、VC、AlN和(Ta0.2W0.2V0.2Mo0.2Nb0.2)C高熵碳化物粉体一起球磨后得到混合粉末，干燥后经过干压和冷等静压成型，用碳粉全包裹住坯体，在1450‑1600℃烧结并保温制得；所述(Ta0.2W0.2V0.2Mo0.2Nb0.2)C高熵碳化物粉体通过Ta2O5、V2O5、WO3、Nb2O5、MoO3、C六种粉体混合球磨，干燥后在1600‑1700℃碳热还原法制得。
