Preparation method of nitride-combined silicon carbide wear-resistant ceramic part for slurry pump
The invention relates to a preparation process of a wear-resistant and refractory material, and provides a preparation method of a nitride-combined silicon carbide wear-resistant ceramic part for a slurry pump. According to the preparation method of the nitride-combined silicon carbide wear-resistant ceramic part for the slurry pump, silicon carbide is used as a main raw material, modified metal silicon powder of which D50 is smaller than 0.5 [mu] m; the addition amount ratio of the modified metal silicon powder to the silicon carbide is 1-10%: 90%-99%; and the modified metal silicon powder, the silicon carbide, a binding agent and water are mixed so as to form a castable, the castable is injected into a mold, vibration casting molding is carried out, and curing, drying, and sintering are performed to obtain the product. The energy-saving and consumption-reducing effects of the ceramic part are obvious; the high abrasion resistance of the material is achieved to the maximum extent; the full-life-cycle service capacity of the nitride-combined silicon carbide wear-resistant ceramic part for the slurry pump is improved; and the nitride-combined silicon carbide wear-resistant ceramic part for the slurry pump is sintered at high temperature and is not limited by the temperature of a use environment.
