| titleOfInvention | Ti (C, N) -based metal ceramic with positive gradient ring core phase and preparation method thereof |
| abstract | The invention discloses Ti (C, N) -based metal ceramic with a positive gradient ring core phase and a preparation method thereof. The outer ring of the metal ceramic ring core structure is rich in W/Mo and poor in N compared with the inner ring phase, and the solid-solution metal elements W/Mo in the ring core phase are distributed in a positive gradient mode from the core part to the outer ring, so that the metal ceramic ring core structure has a positive gradient structure with opposite components compared with the conventional ring core phase. Compared with the Ti (C, N) -based cermet of the conventional ring core phase, the positive gradient ring core phase structure can improve the interface wetting and bonding strength of the ceramic phase and the bonding phase, reduce the lattice mismatching degree of the interface in the ring core and effectively improve the strength and the thermal shock resistance of the Ti (C, N) -based cermet. On the basis of keeping good obdurability, the metal ceramic has higher obdurability and thermal shock resistance than the conventional metal ceramic, can improve the surface processing precision and prolong the service life of the cutter, and is widely applied to the fields of bearing materials, cutting cutters, mold materials and the like. |
