Silicon nitride combined silicon carbide sintered ceramic material for pump and preparation method of silicon nitride combined silicon carbide sintered ceramic material
The invention discloses a silicon nitride combined silicon carbide sintered ceramic material for a pump and a preparation method of the silicon nitride combined silicon carbide sintered ceramic material for the pump, and the ceramic material comprises the following raw materials in parts by weight: 55-70 parts of silicon carbide particles; 10 to 15 parts of silicon powder; 5 to 15 parts of silicon iron chromium alloy powder; 5 to 10 parts of water-soluble phenolic resin powder; 5 to 10 parts of purified water; 0.5 to 3 parts of a defoaming agent; 3-5 parts of a sintering aid; and 3-5 parts of a dispersant. The preparation method comprises the following steps: uniformly mixing raw materials, injecting into a mold, and curing at room temperature; drying at 50-180 DEG C for 1-7 days, and demolding; then heating to 1350-1450 DEG C, preserving heat and sintering; and finally, repeating vacuum infiltration treatment and drying operation for 2-3 times to obtain a target product. According to the ceramic material prepared by the method, the hardness of the surface of a ceramic part is remarkably improved, so that the wear resistance of the surface of the ceramic part is improved.
本发明公开了一种泵用氮化硅结合碳化硅烧结陶瓷材料及其制备方法，该陶瓷材料，各原材料的重量份数为：55～70份的碳化硅颗粒；10～15份的硅粉；5～15份的硅铁铬合金粉；5～10份的水溶性酚醛树脂粉；5～10份的纯净水；0.5～3份的消泡剂；3～5份的助烧剂；3～5份的分散剂。该制备方法为：将原料混合均匀后注入模具内室温固化；然后在50‑180℃下干燥1‑7天后脱模；再加热至1350‑1450℃保温烧结；最后重复进行真空浸润处理和烘干操作2‑3次，得到目标产物。本发明方法制备的陶瓷材料，显著提高陶瓷件表面的硬度，从而提高了陶瓷件表面的耐磨性。
