Two-dimensional transition metal titanium carbide material reinforced ceramic composite material and preparation method thereof
The invention relates to the field of materials, in particular to the field of ceramic composite materials, and particularly relates to a preparation method of an aluminum oxide, zirconium oxide, silicon carbide and silicon nitride ceramic composite material. According to the invention, a novel two-dimensional transition metal titanium carbide material (MXene including Ti3C2 and Ti2C) is used as atoughening phase, and Al2O3 MXene, ZrO2 MXene, SiCMXene and Si3N4MXene composite ceramics are prepared through spark plasma sintering. The preparation method comprises the following steps: 1, preparing an MXene compound: preparing a Ti3C2 or Ti2C MXene compound from a prepared or purchased ternary layered compound Ti3AlC2 or Ti2AlC through hydrofluoric acid corrosion; and 2, mixing ceramic powder(aluminum oxide, zirconium oxide, silicon carbide or silicon nitride) with a Ti3C2 or Ti2C MXene compound according to a weight ratio of (95-60): (5-40), adding a proper amount of a sintering aid, and mixing the raw materials for 5-20 hours by a physical mechanical method; drying the mixed powder and then putting the powder into a graphite mold to be subjected to cold press molding, and applyingthe pressure of 10-20 MPa; and sintering in a discharge plasma sintering furnace at the heating rate of 10-50 DEG C/min, the sintering temperature of 1400-1600 DEG C, the sintering time of 30-120 minutes and the sintering pressure of 10-50 MPa, and then cooling to the room temperature along with the furnace to prepare the Al2O3 MXene, ZrO2 MXene, SiCMXene and Si3N4MXene composite ceramic.
